Boy, that's a good point. I wouldn't have thought of it, but it rings true. Shrill voices.
PS- I see by your handle that you've put considerable thought into the matter.
I haven't studied the book or anything; I don't know what a college expert would say it means, but I own a copy, I read it about once a year, and it gets me in my heart every single time. I refuse to watch a movie version of it because I don't want the pictures in my mind tainted by any Hollywood version. I cherish the book, and when I get done reading it, I am inspired to try harder to be a better person, you know, even when no one is looking.
