Little kids do, I guess, but adults generally see that sort of question as just plain weird. I think of this sometimes when my students friend me on Facebook—adding yet another layer of complexity to the question of how best to balance the teacher-student-friend relationship—a layer of complexity that just five years ago did not exist.
