I got a call one evening from my sister, Rina. “Hey, Jake! Congratulate me!”
I couldn’t help smiling at my sister’s exuberant voice. “Congratulate you for what?”
“I’ve been offered a new job! An analyst position for a big corporation. Their building is only a few blocks from yours.”
“Well, congratulations! Tell me all about it.”
Rina told me about the job, which sounded like a big step up from her current job. She was very excited about it, but then again, Rina was the sunny, easily excited type.
As we talked, I wondered why she had called me to tell me that she had been offered it. We weren’t that close. She was three years younger than me and had annoyed the hell out of me growing up. Once I had a job and permanently moved out of the house, we had gotten along better, but we mainly communicated with each other through Mom.
I asked, “So, are you going to take the job?”
Rina’s voice turned serious. “Well, it depends on you.”
“On me?”
“I don’t like driving in heavy traffic. I don’t know how you handle driving downtown every day like you do. Driving down for the interview, I almost turned around because I hated the traffic so much. But after the interview, I realized your building is close to theirs. Would you be willing to drive me to and from work?”
This floored me. My sister taking a much better job was dependent on me?
I asked, “How would this work?”
“I’d drive over to your apartment in the morning, arriving when you’d normally leave. You’d drive us downtown, then drop me off at my building on the way to yours. Reverse in the evening. I’ll pay for half of your commuting costs.”
That sounded reasonable. Still, I didn’t want to be responsible for getting my sister to work every day. “You live a good thirty minutes from me.”
“My lease is up at the end of the month. Nathan doesn’t care much for my apartment.” Nathan was Rina’s boyfriend, and they had recently started living together. “We’ll find an apartment closer to you.”
“What if I have to work late? I work late once every week or two.”
“Then I’ll work late too. Or I’ll walk around downtown for a while. Just call me in the afternoon if you have to work late.”
I didn’t want to say yes, but I felt like I’d be a total dick to say no. “Okay. I’ll drive you to work.”
“Oh, thank you, thank you, thank you, thank you, Jake!” My sister sounded over the moon. “You don’t know how happy this makes me! You’re the best brother ever!”
I smiled. It warmed my heart to make my sister so happy. “And you don’t have to pay me anything. It’s not like taking you to work will cost me anything.”
“Wow! I really appreciate it. I’m going to go call Nathan and then Mom. Thanks so much! You’re so wonderful!”
Monday a few weeks later, my sister was waiting for me when I got to my car. I had never seen her dressed for work before, and I was struck by how professional she looked. She was wearing a white, button-down-the-front cotton blouse and a gray skirt that came down to her knees. Very basic and simple, flattering her slim body without overly emphasizing her curves. Her three-inch heels cut our height difference almost in half. With her pretty, smiling face and her short, dark blond hair, my sister looked like the stock photo of a young businesswoman.
I unlocked the car, and we both got in. Once we were seated, Rina handed me a brightly wrapped box and said, “A thank you for driving me.”
I smiled, strongly suspecting what she had given me. I collected Pez dispensers, mostly Star Wars and Marvel. They were what my family gave me for my birthday and Christmas; it beat getting a gift card or a sweater.
When I started to open the present, Rina slapped my hand and said lightly, “Not now. We’ve got to get to work. I don’t want you to be late because of me.”
I gave my sister a questioning look, but she seemed to be serious. I handed her back the present and started the car.
As I backed out of the parking spot, Rina said, “Besides, I want you to spend all day wondering which one I got you.”
I snorted.
We spent the whole hour-long drive talking. Rina told me about Nathan and the apartment they were going to move into. I told her about the girl I had just started dating, Ginny. It felt like we hadn’t driven very long at all when I pulled up in front of Rina’s building. I was surprised at how much I had enjoyed having my sister ride with me.
Over the next three months, carpooling with Rina worked out better than I expected. I really enjoyed talking with her. When I had to work late, Rina found things to do until I was ready to go. Given how well we were getting along, I happily volunteered to help her and Nathan move into their new apartment.
Every week, Rina gave me a gift of some sort as a thank-you for taking her to work. After I helped her and Nathan move into their apartment, Rina insisted I give her a key to my apartment. The gifts became a casserole in my refrigerator or a cleaned bathroom. Rina never told me what the gift was. If it was a present, I had to wait until I got back home before opening it. If it was something she did in my apartment while I was out with Ginny, I’d have to wait until I got home to find out what it was. Her love of surprising me was ironic as she didn’t like surprise changes.
And then both our lives fell apart. I got a new boss, Janice, and she was the Boss From Hell. She worked long hours and demanded all of her employees do the same. Suddenly, I was working late every night and many weekends. At first, I tried to keep going on dates with Ginny during the week, but it super pissed her off that I was constantly late or had to cancel. Nathan didn’t like Rina getting home late. Rina tried commuting by herself a few times, hated it, and told Nathan he’d have to accept that she’d be home late, and he’d have to make his own dinner during the week.
A few months into Janice’s reign of terror, Ginny broke up with me. A month later, Rina broke up with Nathan. I helped move Rina into a two-bedroom apartment that she shared with a woman named Maria. Whatever furniture Rina didn’t take with her, I wound up buying from her and Nathan. I felt guilty about being the cause of their breakup. Rina said, “Don’t worry about it. It’s better I found these things out about Nathan before we got too serious.”
“These things?”
“I don’t want to discuss it. It got scary, and I had to get out. I still don’t want to think about it.”
A week later, Rina was waiting for me by the car with one of the boxes from her recent move. It was taped shut. I asked, “What’s in that?”
“A surprise.” Rina put it in my back seat. “Take it to your office. I’ll open it for you tonight.”
Rina had made a habit of getting us dinner before coming over to my building. I’d sign her in, we’d eat dinner together in a conference room close to my office, and then she’d hang out there until I was ready to go. So, I’d have to have the box in my office the whole day with no idea of what’s in it.
Rina also put in the back seat a big, insulated lunch box. It was about half the size of the moving box. I asked, “Another surprise for tonight?”
Rina gave me a smirk. “You got it.”
I shrugged. Whatever the surprises were, I knew they’d be good ones.
She also had a small bag. I asked, “Is that a gym bag or another surprise?”
“A gym bag. My company has a five-thirty aerobics class. I thought I’d start attending now that I know I’ll be staying late almost every night.”
“Okay.”
I wasn’t very talkative as we drove downtown. Rina asked me, “You’re so quiet. What’s bothering you?”
I had been kind of hoping she’d ask. “A friend called me last night. He had seen Ginny at what had been our favorite restaurant holding hands with some guy.”
“Oh, I’m sorry,” Rina said in the perfect way, full of caring and not condescending. She gave me a small pat on the shoulder and said, “It’s been a while, but I’m sure it still hurt. I miss Nathan at times.”
“Thanks.” I meant it. Rina had made me feel a lot better. “And thanks for not giving me a ‘you’ll-find-a-new-girl-soon’ speech.” To inject some levity, I added, “If Janice is going to have us work all these hours, she should do things to encourage office romances.”
Picking up on my new tone, Rina grinned and asked, “Such as...?”
“She should set up a cube with high walls and a door that two coworkers could slip into for a little fun. I might get some action if we had one.”
Rina giggled. “And do what, put a ‘Janitor Closet’ sign on it? With a little sign you could flip over that says, ‘The Janitor Is In’ when you’re using it and ‘The Janitor Is Out’ when it’s free.”
I chuckled. “Maybe ‘Presentation Supplies’ instead of ‘Janitor Closet’.”
We discussed different possible room labels and their corresponding signs to indicate if they were in use or not. Rina did a lot of giggling. My mood brightened considerably.
I’ve known a few women who were nervous gigglers. I found them so annoying. My sister’s giggles weren’t like that. Her giggles were her way of saying she was having fun with me; they were an encouragement to continue being silly or witty. When I heard her giggle, I couldn’t help smiling.
Rina changed the subject by saying, “I was always disappointed your Ginny didn’t have red hair. I think there should be a law that all Ginnys have to have red hair because people can’t help picturing them as redheads because of Ginny Weasley.”
I laughed. “I suggested to Ginny several times she dye her hair red. If you’re going to use the name ‘Ginny’, you should look the part.” I chuckled at the memory. “It pissed her off every time.”
Rina cracked up. When she was done laughing, she asked me seriously, “What would you think if I dyed my hair red?”
I shot my sister a questioning look. “You don’t need to.”
“But I want to. My hair color is so boring. I’d think it’d be fun to be a redhead. At least for a while. See if it gets guys’ attention.”
“If you want to get guys’ attention, start wearing shorter skirts.”
My sister shoved my shoulder. “I don’t want that type of attention. I want guys looking at my face, not at my legs. Or my butt.”
Around seven, Rina surprised me by suddenly appearing at my desk. I asked, “How did you get past security?”
Rina smiled and then gave me a saucy look. She was clearly pleased with herself. “I’ve been buying a cookie when I buy us dinner and giving it to the security guard when I arrive. Today, I gave him two cookies I baked last night. He told me he’d sign me in, and I could go up.”
I couldn’t help chuckling at her latest victory over life’s little challenges. “You’ve got him wrapped around your little finger now.”
Rina put her hand on the back of her head and struck a pose. “Men are suckers for pretty girls bearing cookies.” She dropped the pose and laughed with me.
I thought it might have been Rina’s clothes that got her past the guard. She was wearing a gray T-shirt, gray shorts, and long black leggings. Not a lot of skin exposed, but her clothing was tight enough that you could see all of my sister’s curves. Definitely eye-catching.
When she was done laughing, she walked over to the box she had given me in the morning, which was on the edge of my desk. She said to me, “Scissors, please.”
As I opened a drawer and got out my scissors, I said, “Several people asked me what was in the box.”
“What’d you tell them?”
“That my apartment complex has started charging for trash pick-up, so I decided to bring my trash to work instead, and I’ll give it to the janitor when she shows up.”
Rina giggled. “And did they believe you?”
“No. But it was my story, and I stuck to it.”
Rina cut through the strapping tape she had put on the box, opened it, and took out a big, stainless steel electric wok. She reached back in and pulled out its cord.
“A wok?” I asked in amazement.
“Yes. I’ve gained enough weight since I began having fast food almost every work night that some of my clothes are getting tight. I decided to start cooking my dinner here instead of buying fast food.” She held up her insulated lunch box. “Dinner is ready to be cooked.”
I thought for a moment and then said, “Let’s go up a floor and use the break room there.”
My sister gave me a confused look as I stood up, but she didn’t say anything. I put the wok and its cord back in the box, and we walked to the elevator. Once we were in the elevator alone, Rina asked, “Why go up a floor?”
“I don’t know if it’s okay to cook with something besides the microwave in the break room. Everyone in my department is still here, so someone might complain about us cooking. Hopefully, almost everyone on the next floor is gone.” The elevator doors opened, and we strode toward the break room. “So, what are you going to cook?”
Rina gave me a smirk. “You’ll see in a minute.”
When we got to the break room, Rina plugged in the wok. She then unzipped her lunch box and pulled out a big storage container. “Stir-fry vegetables.” She pulled out a container that was full of a dark liquid. “Sauce.” She pulled out a small container. “Oil.” She pulled out one more container. Tofu.”
“Tofu?”
“Yes, tofu.” She poured the oil into the wok and then added the tofu. “Someone at work has been eating vegetarian for a year now. She’s been telling me she’s lost a lot of weight since switching to vegetarian, and she feels so much better.” Rina moved the tofu around in the wok.
The tofu looked very unappealing to me. Like cream cheese trying to pretend to be meat. I said, “What if I don’t want to eat tofu?”
Rina shrugged. “I’m making my dinner. I’ll make enough for two. If you don’t want to have some, you can have something delivered.”
Rina was acting nonchalant, but I suspected she really wanted me to eat the tofu and veggies. She didn’t like eating alone, and I didn’t want to abandon her by ordering dinner.
“I’ll give it a try. No promises.” Rina gave me a guarded smile. I decided to change the subject by asking, “How was your day?”
“Great!” said Rina enthusiastically. “Deion showed me how to use slicers in Excel. I had never used that feature before.” Rina explained what slicers were and how they would make some of her work so much easier, and then about how helpful Deion and the other people in her department were. My sister loved learning new job skills. In her prior job, she had felt like a glorified data entry clerk. Rina was very career-oriented and had told me during our commutes about new positions she was going to pursue at her company once she had more experience and skills.
Eventually, Rina put the tofu and vegetables onto two plastic plates. She gave me one and a fork, then took a bite of hers. I steeled myself as I took my first bite.
After a couple of bites, I said, “This is good.”
Rina gave me an unconvinced stare.
I said defensively, “All right ... it’s okay. I like it enough to finish it.” I added appreciatively, “It’s nice having a home-cooked meal, and it’s much better than something I could microwave here.”
That got me a warm smile.
We didn’t say anything more. Once I cleared my plate, Rina asked, “Do you think I could store my wok here?”
“If we can find an empty space, I don’t see why not.” I opened a cabinet above the counter, and the top shelf was empty. “Let’s store it there. If someone pitches it, I’ll buy you a new one and keep it at my desk.”
“Sounds like a plan. Now, go back to work while I clean up.”
Rina was all giggly when we started driving home. Finally, she said, “I can’t believe I got you to eat tofu. Eat it and like it.”
I shrugged defensively. “It wasn’t on my list of things I wanted for dinner, but I was willing to give it a serious try because it had a secret sauce.”
“A secret sauce?”
“That you had made it. I know you’re a great cook, and I trust you.”
After a few moments, Rina said a heartfelt “Thanks.” Then Rina added lightly, “I never would have gotten Nathan to eat tofu.”
“I appreciate you choosing to cook for me. Beggars can’t be choosers. If you want to go vegetarian, I’ll suck it up and eat vegetarian even if I’m not thrilled about it. It’ll still be much better than eating some microwave meal like my coworkers do.”
Rina was quiet for a while before eventually asking, “How was your day?”
“Bad,” I said bitterly. “Stupid bad.”
“Stupid bad?”
I shook my head in disgust. “We had a departmental meeting today. Last month’s metrics were down. They had gotten better each month since Janice took over, and she was upset about the backslide.”
“Okay.”
“She wanted to know why our metrics were down.”
“And did someone say everyone was burnt out from working long hours?”
I smiled at my sister hitting the nail on the head. “No. But someone did suggest hiring one or two more people to help with the workload.”
“What did Janice say to that?”
“We don’t need more people. We just need to work smarter.”
Rina asked cautiously, “What did you think of her answer?”
“I found it insulting. Like I was intentionally working dumb before and needed Janice to prod me to work smarter.” A bad taste rose in my mouth. “Some suggestions were made, and most of the meeting was squabbling about whether they were good ideas or not. And at the end, Janice said she wants us to work more hours.”
From then on, Rina would text me when she got to my building, and I’d meet her in the break room on the floor above.
One Friday night, I walked into the break room as Rina was unloading the items for dinner. I asked, “How’s it going?”
“Good.”
Rina was wearing her usual post-workout clothes. At some point, I had started checking out my sister’s body when I joined her in the break room. Her back was always to me. I wasn’t checking her out like I’d check out some woman walking down the street. I mean, she was my sister. I was just keeping myself appraised as to the results of her exercising and eating vegetarian. And the results were very, very nice.
When Rina turned around, she asked, “Do you like it?”
“Like what?” I suddenly noticed that my sister’s hair was now a dark red. I embarrassingly realized that my eyes had never made it above her waist.
Rina’s face fell. I could tell that I hurt her by not noticing her new hair color. I tried to cover my screw-up by asking, “Were you asking about your hair color or your hairstyle?”
Rina’s face brightened. “Mainly the color. The style didn’t change that much.”
“I like it.” I moved around to look at my sister from several angles. “The color is very vibrant and really brings out the blue in your eyes.” I looked a little more. “Your hair has enough color variation to look natural.”
Rina gave me a grateful smile. “Oh, great! I did it at lunch today.” She gently touched her hair. “One of the many advantages of working downtown is that the top-notch hair salons are close by.” My sister looked uncertain. “It looks so different. I’m not used to it. It looks so wrong to me when I look at myself in the mirror. My female coworkers loved it, but they could have been just being nice.”
I gripped my sister by her shoulders and held her at arm’s length. “It looks wonderful on you. It really suits you. Before, you were pretty. Now, you’re a heartbreaker.”
I let go of my sister. She looked down bashfully for a few moments and then returned to cooking. I moved to her right and was looking at her side as she cooked. She said, “I was really hoping the man in my life would like it.”
That was an odd phrase. I bent forward so I could see her face as she cooked. “The man in your life?”
“You’re my brother and all that, but you’re also the guy I talk to the most.” She paused there, and I felt like she had more to say, so I stayed bent forward. Rina also bent forward as she stirred the contents of the wok. As I waited, my eyes were drawn to her chest. Rina was wearing a polo shirt that was tight enough on her that it emphasized her tits, and she had enough buttons undone at the collar to show an appealing amount of skin. If she bent forward a little more, I’d be able to see her bra.
I moved back and turned to face the entrance to the break room. I felt guilty for ogling my sister. I hadn’t meant to, and even though it had just happened, I knew Rina would have been disappointed if she had caught me. My sister was attractive, and it was easy to admire her good looks, but I had slipped into the habit of admiring her nice body far more than a brother should. I needed to do a better job of keeping my mind from wandering when I was around her.
Should I have called my sister a heartbreaker? What kind of brother tells his sister she’s a heartbreaker? It seemed wrong, but at the same time, what was wrong with telling her the truth?
Then I had a sudden thought - Rina was a conservative dresser. And yet, she had on a polo shirt that was tighter on her than anything she wore to work, and she had it fully unbuttoned. She hadn’t intended for me to get a good look down her shirt ... had she?
That was craziness. I needed to pull myself together. Too many long days at work. I was too easily distracted now.
Rina continued cooking. By her posture and how she was moving, I could tell she wanted me to say something. But what?
She had just told me that I was the man in her life. I guessed she wanted me to reciprocate in some way. Was Rina the woman in my life? She was the woman I spent the most time with and the woman whose opinion I valued the most. Still ... it wasn’t a phrase I’d feel comfortable saying. But I felt like I should say something that expressed how I felt toward Rina. I reached out and gently pulled on her shoulder. She set down her spatula and turned toward me as I pulled her into a hug. I said, “You’re the bright spot in my life right now. I’m glad my opinion means a lot to you. Your opinion means a lot to me.”
Rina leaned hard into me as she let me hug her. She said, “I enjoy spending time with you. Before I started commuting with you, I never thought about doing anything with you when I had free time. Now, I regret how little you were in my life.”
“I think we had to grow up enough that we could interact as adults instead of siblings for us to enjoy being with each other. And I do enjoy being with you.”
I felt odd hugging my sister. That was not how our family behaved. We were the stoic type that never complained and rarely showed emotion. I couldn’t remember my parents telling me that they loved me or Rina that they loved her; they were the types to let their actions show their love. I had told only one girlfriend that I loved her, and that was after dating her for almost a year. I never told Ginny that I loved her. I wouldn’t be surprised if Nathan was the only man that Rina had said I love you to. Yet here we were, hugging like this was perfectly normal for us.
I gave Rina a quick squeeze and then released her. She went back to cooking. I said, “I’ve got big news to tell you on the drive home.”
My sister gave me a questioning look before saying tentatively, “Okay.” I hoped she realized my news was something I didn’t want overheard.
Rina changed the subject by saying, “Maria is having a party tonight. I don’t like being home during her parties.”
“How come?”
“It’s mostly friends of her boyfriend. I feel like they spend all night hitting on me.”
Given how good my sister looked, I wasn’t surprised the guys would hit on her.
I said, “You could stay in your room.”
“That’s what I do. But regularly a guy will knock on my door and tell me to come out and join the party. I’m getting tired of making polite excuses for not doing so.”
“I can see that getting old.”
“Could I please stay at your place tonight? I’ll sleep on the couch. I’d much prefer a quiet evening to having to listen to Maria’s party.”
I asked in fake outrage, “Are you saying that my Friday nights are boring?”
“Well, uh...”
I winked and said, “Sure you can stay. It’ll be nice to have some company.”
“Great! Thanks so much.” Rina bounced happily a couple of times and then gave me a quick kiss on the cheek. “I’ll drive home after we get to your apartment, grab some stuff, and drive right back.” She poured the contents of the wok onto two plates. “Let’s eat!”
Later when we got into my car, Rina asked, “So, what’s the big news?”
I started the car and began driving. “We had a departmental meeting today, and Janice announced we’re going to get low-wall cubes next month to foster teamwork and improve communication.”
After a while, Rina said, “So.”
“So ... one of my coworkers said he had worked someplace which had low-wall cubes before coming to us, and that you heard every conversation and every phone call going on around you. He found it impossible to seriously think with so much noise. I added that I speak to people outside of our department and outside of the company much more than people within my department, so improving my inter-departmental communication isn’t going to help much. All my coworkers agreed with me.”
“And what did Janice say to that?”
“People’s voices aren’t going to be a problem because they’re going to pipe in white noise.”
Rina said with a hint of amazement, “They’re going to solve the noise problem by adding more noise?”
“Oh, yeah. Makes a ton of sense, doesn’t it?” I could feel my frustration rising. “I think it’s all about control. Janice wants to be able to stare down our row of cubes and make sure we’re all busy.” I forced myself to relax my hands on the steering wheel. “Janice is a terrible manager. She doesn’t inspire me in any way. Everyone hates working for her. She hasn’t done a thing to make us more productive. All she’s done is make us work more hours. That doesn’t take any skill, any talent. All that takes is being cruel and heartless with no life.” I took a big breath to calm myself. “I’ve had it. I really like my coworkers, I enjoy my work, but I can’t take Janice anymore. I’m going to update my resume this weekend and look for a new job.”
Rina was quiet for a while, and then she said in a small voice. “I love my job. I’ve been learning so much, and I feel really appreciated there. I can see myself building a career there. If you got a job someplace else and stopped driving downtown, I don’t know what I’d do.”
We were quiet for a while, and I eventually said, “Would you like me to find another job downtown?”
“Would you?” Rina said excitedly.
“No promises, but I’ll make downtown my primary search location.”
“Oh, that’d be awesome!” My sister twisted in her seat, leaned over, and hugged me. “That would mean so much to me.”
I hadn’t thought about how a new job might impact our carpool situation. But now that Rina mentioned it, I definitely wanted it to continue. When I drove to work on weekends, I found the drive so boring and empty. It was like the commute with Rina was all bright colors, so full of life; but without Rina it was lifeless, all drab grays.
Rina said, “We’ll work on your resume tonight.” She added excitedly, “Tomorrow, you find some job openings you’re interested in, and I’ll help you with a cover letter. I’ll do whatever I can to help you find a new job.”
I jumped up from my computer when I heard Rina put her key in my door lock. By the time she got the door opened, I was there to help her with her stuff. My sister dumped her stuff on or next to the couch and then walked over to my Pez dispenser collection.
What had convinced me to get this apartment was that it had three long shelves on one wall. The bottom shelf had my Star Wars Pez dispensers, the middle one had my Marvel Pez dispensers, and the top one had the rest of my Pez dispensers. I really liked how the shelves displayed my collection.
When I joined Rina in front of my collection, she asked, “Which ones are new?”
I pointed out the three I had purchased since the last time she had been over. She picked each one up, examined it, and put it back. My collection would be more valuable if I kept the dispensers in their original packing material, but I enjoyed playing with them too much to care. Rina picked up one of my Princess Leia dispensers. Those were her favorites.
I said, “Ginny could never understand why someone would have a Pez dispenser collection.”
“It makes you happy. What’s there to understand?” She set down the Princess Leia dispenser, turned to me, and said, “I’d like my boyfriend to have a collection of some sort. Then when he had a bad day at the office or was grumpy because I had nagged him to do something he had promised to do, I could talk about his collection to put him in a happier mood.” Rina walked toward my computer. “How’s the resume going?”
“Pretty well. I’ve got down what I want to cover. Now, I need to fine-tune it.”
