General All-Purpose Insult: It is surprisingly hard for people to distinguish their left from their right. To help keep things straight, here's two bits of advice. (1) A left turn means to put your nose above your left shoulder and to follow your nose (if all else fails, tape a label on your shoulder). (2) Most of the simple moves involve passing your partner on the left in order to reach the other side of the slot (thus we're all acting like Brits instead of Yanks when we try to avoid head-on collisions).
