He's been shooting hoops with me on the little fisher price hoop. After some of his shots, he will run and fall next to the hoop. At first I thought it was just a hyper 3 yr old thing. But then he just lays there on his back, and sticks his hand in the air looking at me. It took me a minute to realize that he waits there for me to help him up, just like a good teammate should do. I guess that stands out to him as a significant enough part of the game. I'll have to pay more attention to make sure I get the teammate part down correctly - giving him the good-job pat on his butt.
