I don't think I've really had anything rude said to me by a stranger to be honest. When I told someone I know that I was pregnant with #2 she questioned how my DS would deal with it 'given the way he is' which annoyed me as I'm not sure what she thinks is wrong with him exactly, but other than that the I've only had a few mildly annoying comments like when DS is getting cranky in the shops or something and people invariably say stuff like 'is it time for his sleep?' or 'is he hungry?' or something like that. No, toddlers sometimes just get stroppy folks!
I reckon the worst things I've had said to me have been on here!
