Story about Goffman that I heard when I was at Chicago: he was a prof at Penn, and he would play tricks with his class, like have his students all meet in the field in front of the library, by a tree or a statue of Ben Franklin or something, and then hide and wait watch them try to sort out what to do as the class was starting later and later — when the students didn’t know each other well, without having any kind of implied or manifest hierarchy between them, in an uncomfortable social situation that nevertheless demanded some kind of resolution.
