Just now Nate has found a piece of stiff paper which makes a pleasing sound when he waves it in the air. He's been waving it back and forth and cackling while kicking both legs and waving both arms for 15 minutes now. Every once in a while he pauses to explore the texture of the thing, then decides to go back to waving it and laughing.
Kids, man. I mean seriously. Who knew it'd be this much fun?
