Pressed against the far wall of her room, he watched her as a mouse would watch a deadly snake.

He shook his head.
"You wanna talk about it?"
He shook his head again.
She smiled gently. "Do you want me to sing Soft Kitty?"
Sheldon considered this for a moment. "That's only for when you're sick," he whispered.
"Well," said Penny. "Losing your virginity at twenty-six years of age... that's a kind of sick."
