My car has a bumper sticker that says “God was my co-pilot, but we crashed in the mountains and I had to eat him.”
Anyway…I was a chubby kid that hit a growth spurt or something in high school and it all evened out, so I’ve been on both sides of the fat/skinny fence. I personally don’t like people commenting about my weight, because it’s still a sensitive issue. I can’t say I’m lucky enough to have had someone walk up and say “you have nice tits/ass/whatever” but I imagine if I did, I’d find some way to utilize the situation to publicly embarass them. Of course, the way I normally dress tends to repel random people talking to me.
About the only thing I ever get comments on is my eyes, which are an odd colour, and I wear very dramatic makeup… I don’t think I’d have the right to be offended by a compliment on something that I deliberately (and obviously) draw attention to.
