The school I was in from 4th to 8th grade, there were 16 people in my class (and, I learned, that many last year when they graduated), and around 200 in the school. Actually, it was a lot like Rifty's situation. Then my high school had a little under 400 people total, with about 80 in my graduating class. Going to that school for the first time was like culture shock - you had to refer to people by their first AND last names sometimes!
