A/N: A very short chapter today. I am struggling with the next one, so it might be a few days or more before the next. Thanks again for the reviews etc it's make my day.

"Penny I don't have any secrets."

Penny looked at Sheldon, she wasn't buying that one. "Yeah, sure you don't, so why are you twitching right now?"

"I'm not." and he looked away from her. "Penny I'm tired and I'm sore I want to go to bed."

"Leonard's been whistling in the apartment whilst you've been away." She had to say something to get his attention.

"Whistling?"

Penny nodded to him, "I bet he is whistling at the party."

"I don't care, leave me alone Penny I need to go to sleep."

Sheldon wasn't going to share his secret with her, there was only one thing left to do, straight out ask. "Sheldon have you ever been in love?"

"I love my mother, my meemaw."

Penny interrupted him, "No have you ever fallen in love?"

"Not this again Penny!"

"Just answer the question and I will not ask it again."

Sheldon sat up and looked down at his hands, he licked his lips, then he looked straight into Penny's eyes. "Yes Penny I did once fall in love. Now leave me alone, i don't want to talk to you about this, it's makes me very uncomfortable."

Penny couldn't believe her ears. "Did the other person know?"

"Penny please you have your answer."

"Did the other person know Sheldon?"

"No, now leave me alone." he tossed himself back onto the bed and turned away from her. "Turn the light out on your way out."

Penny stood up and decided that she should leave it, it was clearly Amy he was talking about and it seems to hurt him still, but Penny can't leave things be. She sat back on the bed and placed her hand on Sheldon's shoulder.

"Sweetie, it is Amy isn't it?"

"No it's not Amy."

"Oh, you sure?"

Sheldon turned to look at Penny. "I think I would know, now please leave me be Penny." he turned away from her again.

"Do I know the person?"

"Penny please I am very uncomfortable with this conversation."

"Sweetie I just want to help."

"How does this help? I know how you can help, you can help by leaving me alone."

Penny came to a realisation, she knew who Sheldon was in love with. "It's Leonard isn't it?"

Sheldon sat up in the bed and looked at Penny. "It isn't Leonard, or Raj or Howard."

"Isn't, not wasn't, so you are still in love with this person?"

"Penny, please."

"Well it certainly isn't me?" she laughed.

Sheldon looked at her and said nothing, he didn't reply and he didn't react to the question.

He sat there for about 30 seconds and then he said "Penny, I am very tired I need to go to sleep, I came here as your friend, I paid for the train tickets and the hotels, I even got my first black eye because of you, all I ask is that you leave me in peace, please."

Penny closed the door of her old bedroom behind her and flopped onto her bed. It was only 11.00pm, she grabbed her phone and rang Leonard, she had to talk to someone, someone that could help her with this.
