It was Thursday, anything can happen Thursday, and Sheldon's friends had decided to catch a late showing of The Green Lantern. Despite his eagerness to see the movie for the third time, Sheldon found himself waiting outside Amy's apartment. It was 10:30 by the time Amy found him in her hallway.

"Hello Sheldon," Amy asked." How long have you been waiting for me?"

"About an hour and a half. I assumed you'd be back from your liaison with Dr. Egan at a decent hour, but I am surprised to find you home so late."

"Would you like to come in?" Amy asked. As Sheldon entered he noticed that she did not appear to be surprised. It was almost as if she expected him to be there, waiting for her. "Make yourself at home."

"Thanks" Sheldon said trying to sound non-chalant as he sat on Amy's couch. "I assume your date with Dr. Egan was satisfactory."

"It was. Patrick is a very interesting person. We talked at length about his exploits in science and his traveling adventures. It was a pleasant evening" Amy came up behind Sheldon and passed him a glass of yoo-hoo. When he took the beverage their hands touched and their eyes met for a moment. They both quickly looked away.

"It seems that this Egan fellow enjoys talking at length about himself. I'm amazed that you could spend so much time with someone so self-absorbed." Sheldon said.

Amy sat beside him on the couch and concealed a smile. "It appears that you are quick to judge Patrick."

"I don't believe I am. My dislike of your friend is based on facts. I dislike his attitude and conceit."

"Have you considered that your aversion to Patrick has nothing to do with his personality that instead it is a defense mechanism to hide your true motivations? Maybe this is really your attempt to assert your status of alpha male?" Amy's line of questioning was reasonable enough and Sheldon was curious where it would lead.

"Please continue."

"Maybe, like all primates your innate impulse to secure and protect your female in this case myself, from male rivals has caused you to behave aggressively." She was embarrassed by her statement but was sure that her reasoning was valid.

"Are you suggesting that I consider Patrick Egan to be a sexual rival?" Sheldon asked flabbergasted.

"I'm not suggesting it; I'm stating it out right. Your behavior since you first heard of my relationship with Patrick has been a text book display of anger and aggression. It appears that you too are a slave to the baser urges you so often deride."

"If I am angry it is only because you have insisted on spending your time with someone so vain and insignificant. You romantic liaison is a sign that you have change from my Amy into a common floozy who's easily seduced by insipid men."

There was a pause as they both realized what he'd just said. They were amazed. My Amy. The words slipped out of him as if they had exited his subconscious.

"I'm going to leave now" Sheldon said getting up. Amy followed him to the door. "Good bye Amy Farrah Fowler"

"Good bye Sheldon Cooper" Amy reached out and shook his hand. The warmth of her skin made him redden and he quickly exited the apartment. Once in the hallway Sheldon felt there was more for him to say.

Amy answered the door before he could call her name. "Yes Sheldon?"

"Amy, I've decided that, assuming your hypothesis is correct, you've behaved badly." He said stepping back into the apartment.

"I can't imagine what you mean. I can't think of any error that I have committed." Amy was truly dumbfounded. She knew that Sheldon had behaved childishly but she could not understand how she had erred.

"You've betrayed me Amy Farrah Fowler" he said finally.

Her confusion worsened, "How have I betrayed you?"

"Do you recall how we first met Amy?" He said following her to the couch.

"Of course I do. We met through a dating site, matched by unsupportable mathematics." Amy thought back to the day that they'd met how surprised she'd been to meet someone that she could really understand and talk to. It was a memory she cherished.

"The purpose of this dating site was to match romantic couples, correct?"

"Yes." Amy said. She was always interested in following his line of reasoning. It was like a social game of counterfactuals.

"And if we were matched by such a site we were meant to begin a courtship. Correct?" She nodded her head and he continued. "In the months following we've communicated on a daily basis, we've gone on a date, I've met your mother and you've met mine and we have completely been integrated into each other's lives."

"I understand that our relationship has resembled a courtship, our friends have made that abundantly clear." "She countered, "But we have always maintained that we are boy/girl/friends and nothing more." Amy was baiting him, hoping that his line of reasoning would lead where she'd hope it would lead.

"Despite what we've maintained, for all intents and purposes you are my girlfriend. We have behaved as such and you have betrayed that social bond. You of all people should understand the social implications of such an infraction. You have behaved very badly, Amy Farrah Fowler."

Amy looked at Sheldon not knowing what to say. Then after a moment, "I guess you are right. I'm sorry…Where do you suggest we go from here?"

Sheldon looked at Amy and tentatively sat closer. "I think I'd like to kiss you." he said making eye contact. Amy smiled and inched closer to Sheldon. With their hands in their laps their lips made contact. At first their kiss was chaste but slowly the impulse to touch grew in them. For the first time in their lives they felt the need to touch, to caress another person. As the kiss grew more passionate Amy stopped them.

"Do you suggest that we consummate our relationship by engaging in coitus?"

Sheldon grabbed her hand and got up. "Well, let us go to your bedroom and we'll see how it goes." With that Sheldon led Amy out of the room.
