I think I'd be really mad if a stranger tried to touch my belly, I'm not at all touchy-feely. But in the UK I think people are ruder.

Must admit, I do know that some people are going to find this hard, and I don't mind the odd jokey comment from them, but I would have a problem with a stranger saying something rude, even if they didn't mean it that way. At least I can blame it on hormones! Nice comments I could live with, but I hate comparisons at the best of times so belly-comparisons will not go down too well.
