When I dropped Sam off at school, I told him that I was going to watch him walk into his classroom. I said feel free to turn around wave to me and do a little dance if you want to.
He's so funny. He was in the gate, about half way up to his class. He turns around waves really big and then starts dancing. To make it even better, he brought his air guitar.
He's a funny little man. He didn't care who was there or who saw him.
