I almost hate to publicize this, but did you know there is a movement
that is pro-anorexia and pro bulimia? I think it's a little like being pro-cancer.
One thing I've learned over my years on planet earth is that you can never know what people actually do, what people are capable of doing, and what goes on in private lives. It's why I find comments by the neighbor of a murderer such as, "we never knew, he was such a nice guy!" to be proof of the fundamental naivete of all of us. It also explains our current politics.
