To my surprise, I played It with eldest today. The surprise was he even knew the game. He must have learned it at his pre-preschool. We were playing outside, playing catch (I introduced him to the concept of diving on a loose fumble, I hope he doesn't try it on his little brother) and all of a sudden, he says "You're It," then ran off laughing. I'm waiting to see if he surprises me by offering to play chess tomorrow.
