I think I read this entire thing on a bus to Stratford when I was in college. Being by Judy Blume, I loved it. I've been trying to remember if this is the book where one character judges others by whether they "get it." It's never explained what "it" is, but I like that idea: that if someone is enough of a kindred spirit, you just know they "get it," and that's all the explanation that is needed.
