I'm posting this in feminism because I don't want to get torn apart on aibu and I think it is a feminist issue too. Today I took DD (8) to the library and she was looking at one aisle while I was in the next one. When I moved around to hers I saw that a man was standing over her (she was crouched to look at the books near floor level). I thought he was a bit rude but probably nothing more. I kept an eye on him and as she moved, so did he, sort of squishing in to the shelves so she couldn't get out. I'd seen enough by then and came forward and he saw me and left. Now, DD thought he was a "rude man" who didn't give her much space but I also felt that she should know that she didn't have to be polite to him because HE was in the wrong. However, trying to explain this I really got tied up in knots - basically trying to warn her against men without tarring all men with the same brush! The more I think about it, the angrier I am - it really wasn't just a case of not understanding personal space. I am convinced it was done on purpose and I really should have said something but it was over so fast.
I knnow this is a much wider social issue but basically my question is: what do you say to your daughters about situations like this? She is very kind and polite and hates to offend anyone - exactly like I was at her age and I can remember a number of unpleasant experiences that I don't want her to have to face.
