The Kids on the Train, the Kids on the Bus.

Presents an essay describing the rude misbehavior of two sets of high school students in two distinct cultures: white prep school boys whose transgressions are written off as harmless, and urban African-American and Asian-American students whose off-putting behavior gets no such exemption. Suggests that this misbehavior and the reaction to it turn on foreknowledge of the students' futures. (SR)
