Facebook is crap anyway. I deleted mine again recently. Well, I started the process to delete it. It takes 2 weeks. But I get similar guff from people over being skinny. I'm able to eat like a horse and burn it off, so people keep saying I have a 'high metabolism' which I'm not sure is rudeness or a compliment. And sure, I look thin - that's true. We cannot help the way we are. People can be over or underweight, and if others don't like you, that's their problem.
