This was where she belonged, sitting next to Sheldon in her 'spot'. He had been talking for what seemed like ages about the plot of the movie they were watching. Penny turned her head at the sound of the front door opening.

Sheldon, of course, had heard the door but choose not to move. "Don't you find it annoying, Penny that, people simply walk in without knocking," Sheldon said without looking away from the TV.

Penny smiled, "Sarcasm, Sheldon?" Looking at his face, she was sure he was smirking.

"No," he replied.

Leonard was standing now just inside the doorway, "I am allowed in without knocking, Sheldon. I live here."

Sheldon stood up, turning to look at his former roommate, "Leonard, I beg to differ. You have terminated your roommate agreement twice in as many weeks. Why should you think you still live here?"

Leonard walked into the apartment and sat in his old chair. Sheldon sat down, arms crossed, waiting for Leonard to speak.

"Ok, maybe I don't live here, but I can still visit right? Anyway I brought our mail up," he threw the mail down onto the coffee table.

Penny felt a little uncomfortable, "Look, I should go. You guys need to talk." As Penny stood up to leave, she was stopped by Sheldon's hand on her arm.

Sheldon glanced over to Leonard, "Penny, I see no reason for you to leave." Leonard simply nodded.

Penny however hardly heard a word he said; her attention was focused on Sheldon's hand which was still holding her arm.

She was not the only one watching Sheldon's hand. Leonard stared at his former roommate, shaking his head,"Sheldon we need to talk about me moving back into the apartment?"

While sitting back down, something caught Penny's eye; an envelope on the table. If there is one thing certain to grab her attention even more than a sign displaying a shoe sale, it's a letter marked: 'Free offer, 1st prize and holiday.'

Unable to hold her inquisitive nature in check, Penny asked, "Sheldon who is 'Executive World Travel?" He ignored her, his attention focused on Leonard. By now Penny had the envelope in her hand, and was waving it in Sheldon's face, "Sheldon who…"

Penny was cut off by Sheldon turning to face her,"Penny, please! 'Executive World Travel' wrongly believes I entered and won a competition run by them." Sheldon turned back to Leonard, dismissing Penny and the envelope.

Penny sat chewing her lower lip, "Sheldon can I open it? Just to see what you've won." Sheldon sighed; he knew she would not let this go.

"Penny, Penny, Penny. This letter is addressed to Dr Sheldon Cooper. I believe the U.S Post-Office will not look kindly on me allowing just anyone to open my mail."

Penny hated being spoken to as if she were still at school. She looked at Sheldon through narrowed eyes, "Open the letter, Sheldon."

Leonard looked on at the exchange going on between his former roommate and his ex-girlfriend and he shook his head.

He watched as Sheldon read the letter before throwing it on to the table, "It's as I said; they insist I've won a holiday. Total nonsense."

Penny snatched the letter up before Leonard could get to it, quickly reading the letter, "My God Sheldon! You've won a holiday for two in Mexico!"

Leonard took the letter from Penny's hand, but her attention now seemed elsewhere. Penny moved just a little closer to Sheldon, before starting her 'make Sheldon go on holiday campaign,' "Look sweetie you really need a vacation. You're always working. You could burn yourself out."

"Penny, thank you for expressing your concern for my welfare, but it's misplaced, I assure you."

Leonard looked up from reading the letter, "Have you read all of this? It's a great holiday, the Mayan Riviera, five star hotel and all expenses paid for two."

Sheldon stood up with a sigh before walking to the kitchen area, and without turning he said, "Clearly then I can't go. Who would I take with me?"

Penny and Leonard both looked at each other and said almost as one, "Take me"

Sheldon was still facing the kitchen, so neither of his friends saw the slight smile that crossed his face.

After making his and Penny's tea, Sheldon returned to the couch.

Penny was the first to speak, "I know you and Leonard have been friends for years, but I'm your friend too, and I so need a holiday in the sun."

Leonard had a smirk on his face, "Penny, its 85 in the shade outside, how much more sun do you need? Sheldon, she is right- we've been friends a long time. We have history."

Penny looked at Leonard, wondering who Sheldon would pick if she punched Leonard in the throat. She turned back smiling to face Sheldon, "The thing is when you're away from home, you need someone reliable with you. That's right, isn't Leonard?"

Sheldon turned his head to look at him, but Leonard could not meet his eyes; he knew what Penny meant.

Penny felt a little sick; she had not meant to be so cruel to Leonard, "Look, guys, maybe both of you should go. It will give you time to become best friends again."

Sheldon had a puzzled look; which did not sit well on the face of a man with an IQ of 187, "Penny, am I to understand you no longer wish to be my best friend?"

Penny was at a loss at what to do next, within mere moments she had been hurtful to Leonard, and now she had upset Sheldon, "Sweetie, being your best friend is the most important thing in the world to me. It's just I don't want anyone to get upset, when you pick me."

Sheldon sat back in his spot and looked at his two friends, "So, you don't think Koothrappali is going to feel left out at all?"

Almost as if on cue, Raj walked into the apartment. He gave out a strangled "Hi" to his friends when he saw Penny sitting on the couch.
