God, I really don't want to teach this afternoon, or this evening for that matter. Still, plough on I must.

For my readership in the far East: Have you noticed how tiny Chinese, Japanese and Korean hand gestures are? When they wave a hand in greeting, the hand waves, but not too much, from the wrist, while the arm remains at an almost parallel line with the body: When they clap, the elbows remain firmly in place at the sides, while the hands do precise little flapping motions. Graceful or just self-control?
