How to be polite, and why

A friend and I came up with a game called Raconteur. You pair up with another Raconteur at a party and talk to everyone you can. You score points by getting people to disclose something about their lives. If you dominate the conversation, you lose a point. The two raconteurs communicate using hand signals and keep a tally on a sheet of paper or in their minds. You’d think people would notice but they are so amused by the attention that the fact you’re playing Raconteur escapes their attention.
