Exercise - characterization. Form triads: one is the moderator, one the target, one the observer. Moderator asks observer "name one thing that struck you about <target>'s character". Observer goes, for instance: "she's funny". Moderator asks for specifics: "what particular things have you observed about <target> to make you say that?". Alternately, ask moderator to pick up on particular observations ("she has this way of pushing her glasses up her nose") and move in the other direction ("what does that tell you about her, if anything"). After a few minutes, switch roles.

This could be a good icebreaker, or a useful adjunct in a module on social skills.
