oh...one more thing. Apparently a swipe of your thumb across your nostril is a sign of annoyance/anger here. Agnes, our bosses wife, wanted more beer last night and Choi didn't want to spend the extra on it and was teasing her. She looked at him questioningly and he ran his thumb across his nose. It was a joke, this time, but Agnes said it usually it's not. My guess is it's somewhere around what the finger would be back home.
