When you get to certain age...................you find it offensive if noone wolfwhistles at you!!!
Ok, ok, that was a joke, my sense of humour.
Seriously, the time I find embarrasing/offensive is when it is a group of lads who are obviously taking the P*, and having a laugh by saying to each other "lets go and embarrass that silly woman" while elbowing each other,
that is annoying because is as if they were laughing at you
But normally i suppose is just funny
