I just really don't like it because I'm not a girl, I'm a woman. I don't find it offensive as such when people refer to grown women as girls, but I do find it frustrating. But I also feel the same when men are referred to as 'boys', particularly when it's used in a belittling cutesy way.
Yes there are of course bigger fish to fry and it doesn't affect my life too much, but am I bu to not want to be called girl? Would I sound like a complete idiot if I correct people? :(
