We were in the apartment. 

"I don't see anything at all, Sheldon." Steph says.

"Well, you're the doctor, but I am constantly hearing this annoying sound." Sheldon says.

"Me, too." I say Leo nods in agreement.

"Is it a high-frequency whistle?" Sheldon asked.

"No, it's more of a relentless, narcissistic drone." Leo answered.

"Yup, there's no inflammation at all, Sheldon." Steph explains.

"Then it must be a tumour." Sheldon tried again.

"I Seriously doubt it." Steph tries.

"Maybe it's a lingering bacterial infection from all those childhood toilet swirlies." I say confused.

"Is that possible? I used to get those all the time. Even in church." Sheldon pipes up.

"Well, you know, if it is from a swirly, there's something I can do. Okay, circle, circle, dot, dot, now you have a cootie shot! I'm going to bed." Steph says.

"Okay, I'll be right in." Leo points out.

"It's not enough that she mocks me, but that isn't even the correct procedure for a cootie shot." I explain.

"Do you understand that Stephanie's not here to treat your imaginary ailments?" Leo asked Sheldon.

"How is it imaginary that I keep hearing an octave above Middle C? Is that imaginary? I don't think so." Sheldon answers.

"Good night." Leo tried

"Leonard, there's one more thing. Under Article One, Section Three of our Roommate Agreement, I'm calling an emergency meeting." Sheldon says.

"No, you're not." I tell him.

"Leonard moves the meeting not occur. Is there a second? None heard, the motion fails. I'd like to begin the meeting by congratulating you on the progress in your relationship with Dr. Stephanie." Sheldon says making me laugh.

"Thank you." Leo continues.

"That being said, we have to discuss the implementation of the agreed upon "cohabitation" rider which has been activated now that the two of you are living together." Sheldon says.

"We're not living together." Leo says making me laugh.

"I beg to disagree. "A girlfriend shall be deemed quote living with un-quote Leonard when she has stayed over for A, ten consecutive nights or B, more than nine nights in three week period or C: all the weekends of a given month plus three weeknights." I say reading it.

"That's absurd." Sheldon says.

"You initialed it. See? L.H., L.H., L.H." Sheldon tried.

"Wait, I only initialed it because I never thought it would happen! I initialed another clause naming you my sidekick in case I get superpowers." Leo says.

"Hmm, yes, you did. Now, to review the following provisions are hereby activated. In the refrigerator, as opposed to us having two separate shelves and one communal shelf, the three of us now get individual shelves and the door becomes communal. Next, apartment vacuuming shall be increased from two to three times a week to accommodate the increased accumulation of dead skin cells. Third, the bathroom schedule. Now, I'm given to understand women have different needs, so, we'll have to discuss that." Sheldon explains making me look up from my comic book confused.

"I'm going to bed." Leo says.

"At least take this with you. Look, and have Stephanie initial here, here, here, here and here. This states that she does not now nor does she intend to play a percussive or brass instrument. Sure it sounds like a tumor pressing on the auditory nerve." Sheldon says. The next day I was say in the kitchen.

"No, absolutely not." Leo continues.

"It's not a big deal. We have latex gloves." Sheldon continues.

"I don't care what the symptoms are, my girlfriend is not going to give you a prostate exam. And I'm sure you're girlfriend feels the same." Leo says.

"Don't bring me into this." I say drinking my coffee before I stand up to make more.

"Hi, Sheldon Alex." Steph says walking in.

"Good morning, Dr. Stephanie. I trust Leonard satisfied you sexually last night." Sheldon says.

"Oh come on! Sheldon, we don't ask questions like that." Leo tried.

"I heard you ask it over and over. How is it inappropriate for me to ask it once?" Sheldon asked making me laugh.

"He did very nicely." Steph answers.

"See? She's not offended. And now you finally have an answer." Sheldon says.

"Out of coffee. Need coffee. Alex where are you?" Penny asks.

"Uh, hello." Steph says as I hand Penny a cup of coffee.

"Hi! Thank you so much Alex. Stephanie, right?" Penny asked looking at me.

"Uh-huh. And, and, and you are?" Step asks.

"I'm Penny, I live across the hall. I've heard a lot about you." Penny answered.

"Really?" Steph asks her making me snicker through my cereal.

"Hmm." Penny answered I could tell this wouldn't go well.

"I haven't heard a thing about you. Leonard? Why haven't I heard a thing about this woman who lives across the hall and comes into your apartment in the morning in her underwear?" Steph asks.

"She's heard about you because we're, you know, involved and you haven't heard about her because... I never slept with her, I swear! And she's best friends with Alex." Leo says.

"In Leonard's defence, it wasn't for lack of trying." Sheldon says.

"Thank you, Sheldon." Leo tells him making me laugh.

"You're welcome, Leonard." Sheldon says.

"Look, I'm just saying, um, Penny is one of our many neighbours, you know, and in our building, neighbours come and go, it's very casual, no dress code. In fact, some mornings I'll just mosey down to the third floor in my pyjamas and have cereal with Mrs. Vartabedian." Leo explains.

"Really? I have never once been invited to have cereal with Mrs. Vartabedian." I explained.

"She doesn't like you. Um, well, uh, you have a gall bladder to remove and I have to get in the shower and Penny has clothes to put on, so..." Leo tries.

"Well, it was very nice meeting you." Steph says. 

"Nice to finally meet you, too." Penny says as I walk into my room. We were in the university cafeteria.

"New pants?" Howard asked him.

"Yeah, Stephanie got them for me." Leo answered.

"Nice. Cotton?" I asked him while eating some of my food.

"Actually, I think it's more of wool, fire ant blend." Leo answered.

"So, the girlfriend's buying clothes for you, huh? Sounds serious." Howard says.

"It is actually. In fact, I gave it a lot of thought and I decided it was time for us to live together. Also Alex buys Sheldon's clothes for him all of the time." Leo says.

"Sheldon is incompetent to buy his own clothes." I tell Leo making him and Howard nod. 

"Uh, Leonard, huge mistake. There's a whole buffet of women out there and you're just standing in the corner eating the same devilled egg over and over again." Howard tries.

"At least I have an egg. What do you have?" Leo asked him.

"A veritable smorgasbord of potential sexual partners. See the blonde over there? I can hit on her and you can't." Howard answered making me laugh.

"So, go hit on her." I tell him trying to be a supportive friend.

"She's not my type." Howard answered.

"Too bad, 'cause she was checking you out before." I told him.

"She was?" Howard asked me.

"Of course not. Look at her." Raj answered looking between me and him.

"I don't care what you guys think, Stephanie and I are very happy living together. I will give either of you 20 dollars, right now to trade pants with me." Leo says. Sheldon drags me to the hospital.

"Sheldon Alex, what are you doing here?" Steph asks.

"I got dragged here." I answered. 

"Hang on. 130 over 80. A little high. We can attribute that to the stress of sneaking past the security desk." Sheldon explains.

"Where did you get the stethoscope and the blood pressure cuff?" Steph asks him.

"My aunt Marion gave them to me for my 12th birthday. She thought if I failed at theoretical physics that I should have a trade to fall back on. And by the way, the blood pressure cuff is called a sphygmomanometer." Sheldon explains. 

"Thank you." Steph tells him.

"Didn't they teach you that in medical school?" Sheldon asked her making me slap his arm.

"I'm kinda busy here, Sheldon." Steph tells him.

"I understand. All I need is for you to authorize these tests." Sheldon says.

"A cardiac stress test, a full body MRI, an electromyogram, a CBC, baseline glucose, upper GI?" Steph asks.

"Oh, and an exploratory laparoscopy. Last time I had hiccups, it felt like my diaphragm was just going through the motions." I answered her.

"Go home, Sheldon. Alex take him home." Steph tells me. 

"Can I at least have the upper GI? I already drank the barium!" Sheldon says as I drag him home. We were in the university cafeteria. 

"Hey." Leo says to us when he joins.

"Hey." Raj stated looking at us.

"Hey. Nice sweater." I stated looking at Leo.

"Yeah, Stephanie got it for me. It's kind of fun." Leo stated.

"It's got a big bird on it, dude." Raj stated.

"Yeah, yeah, that's the fun part. We're also getting new curtains for my bedroom, and a dust ruffle, and a duvet, and I don't even know what a duvet is but I'm pretty sure if I did I wouldn't want one, but every time I talk to her about moving out she cries and we have sex." Leo explained.

"You're lucky. With me, it's usually the other way around." Raj stated making me laugh.

"You know, if you can't talk to her, why don't you just text her?" I asked Howard.

"Isn't that kind of cowardly?" Leo asked looking at me. 

"Oh, yeah. It's beyond contemptible." Howard answered.

"It's true, but on the other hand you are wearing a bird sweater." I stated.

"Sold. "I think it would be better for our relationship if you moved back to your place." There. It's done." Leo stated making me laugh.

"Good for you." Howard says.

"Yeah, good for me. I'll never have sex again. (Phone buzzes) I was wrong. See ya." Leo says making me laugh.

"Good luck." I stated.
