I'm pretty skinny and people are always commenting on it. My friends don't call me anorexic but they say sarcastic stuff like, "God, you're so huge. You need to go to fat camp." I really don't think this is funny at all. One of my friends said something like, "It's only funny to call someone fat if they are really skinny," and I said, "I don't think so," but they STILL don't get it! What do I do?
