Thanksgiving, our eminent moral holiday, doesn't have much for children. At its heart are conversation, food, drink, and fellowship - all perks of adulthood.

I've always been - as a teacher, as graduate student, as a student, and I think, really, as a child - I've been interested in poems, but not so much for what the take home pay is, what you might sum up from them in moral or intellectual terms or whatever, but what's in the certain lines and how lines relates to other lines.
