The school week was bad enough. But the existence of Saturday meant the existence of Saturday night. That’s when Dan really felt it most. Walking through town, hearing other kids having fun, enjoying parties or playing games or just hanging out and talking, Dan felt like he was on the wrong side of a glass barrier. Usually, he stayed home and watched television or read a book. Sometimes, he went for a walk. This Saturday, as spring ended and the airwaves filled with summer reruns, Dan decided to go out. The moment he opened the door, he heard laughing and shouting. One house away, at the Emersons’, kids were playing in the pool. It should be easy, Dan thought. All he had to do was walk up to Nicky Emerson and say hi and start talking. That’s all. They’d been neighbors for years, but they never did anything together. That’s the way it was. Dan didn’t know why. Most of the time, he didn’t even really mind. At least, not too much. But Saturday nights were tough. Dan walked. He passed through his own neighborhood, traveling as unnoticed as a gum wrapper blowing across the pavement.
