I sometimes entertain myself by looking at stranger's profiles on MySpace™. The same sort of thing one does when commuting on a crowded bus. You look around, wonder about why people put on the public faces they do, hypothesize about what they're really like. It's just a game. Since I've retired, I don't ride buses and trains very much, anymore, and mission-shopping at grocery and department stores doesn't provide as many opportunities for that kind of entertainment.
