I'd forgotten that I made this video a couple of weeks ago. This is the class of brainboxes I have every afternoon. In order of appearance: crazy Mark, super-smart Kelvin, shy Jackie, moody Jenny and Clara, for whom I can't come up with an apt adjective. They're so much fun, and they work hard too, usually. I sometimes have to use my ninja tae kwon do moves on Mark but he gets on. On Monday Kelvin was teaching me about the American revolutionary war. I mean come on! You're Korean and you're nine! He couldn't grasp the fact that I was pro-William Howe, and called George Washington a pussy. But what are you going to do?
