A/N Okay. I still don't own these characters but am borrowing them again.

I am probably writing a story no one will like, but I need to get it out of my head. It will be Shenny to start and then eventually Lenny.

Dr. Leonard Hofstadter thought he was completely ready for what he would face in attempting to become Dr. Sheldon Cooper's roommate. He had talked to all his ex-roommates and all those who tried and failed. He also felt prepared for the actual job of living with him. He knew who he was and how he acted. While it was true he was still one of the few individuals at Caltech who had not been putdown by Dr. Cooper, he figured his experiences with his mother would enable him to cope.

Of course, the question others would ask him was, 'Why would you put yourself through it?' All the ex-roommates had to admit the apartment was really nice and the rent was very reasonable. And then Leonard had to admit he was curious how it would be to room with Dr. Cooper. In spite of how they found him obnoxious and condescending, everyone also agreed he was one of the smartest individuals they knew. Leonard was also fascinated by Sheldon's childhood and his Eidetic memory.

And now as he sat there signing the roommate agreement, he congratulated himself that everything had gone pretty much as he expected. He was actually enjoying going through this ridiculous document, finding most of the things interesting.

It was at that moment that his life changed forever. She came through the door without knocking, and with his first look, he was lost. It wasn't just that she was flat out gorgeous even in the ugly uniform she was wearing, but there was something about her that he sensed immediately. And nothing she would ever do would change how he felt about her from that first moment.

But who was she? Why did she just come in without knocking?

She was speaking at she came in, "Shelly, I stopped off and got supper. It was so slow at work they had me leave early."

Then she saw Leonard, and obviously surprised, said "Hello."

Leonard managed to stammer out a "Hi."

"Shelly, aren't you going to introduce us?"

Sheldon turned to face her, obviously irritated that the process had been interrupted. "You know I do not appreciate you calling me Shelly." When she just smiled at him, he sighed and said, "Leonard, this is my girlfriend Penny. Penny, this is Dr. Leonard Hofstadter, my new roommate."

Leonard's mind reeled, this goddess, the love of his life, was Sheldon Cooper's girlfriend? How could that be?

Penny smiled and said, "Glad to meet you, Leonard, I hope you know what you're getting into."

Sheldon said, "Yah, Yah, we know. No one wants to be Sheldon Cooper's roommate." He looked pointedly at Leonard, "May we get back on track?"

Leonard nodded and turned back but his mind was still churning. Did she live here with Sheldon? He now began to doubt whether this had been a good idea. How could he stand seeing them together? How about if they had sex? He was almost ill thinking about it. Reluctantly, he returned his mind to finishing up the agreement.

Penny put the food in the kitchen and told Sheldon, "While you finish that up, I'm going to go home and change." Then she asked, "Leonard, do you want to stay for dinner?"

Sheldon quickly spoke up, "He can't stay, we don't have enough food."

Penny answered, "Oh, we can figure something out, he can have some of mine."

Leonard was relieved, she didn't live here. But he decided he wasn't ready for supper and seeing them together. He had to be alone and figure all this out. "Thank you, Penny, but I have plans."

Penny nodded and went out the door. As they finished up going through the agreement, she returned wearing shorts and a shirt that showed some cleavage. Leonard tried valiantly not to stare. He knew he had to get out of there.

He quickly said his goodbyes, telling Sheldon he would get his key from him at work, and then he was gone.
