An actual conversation which just took place directly in front of the box office between two six(ish) year old girls:
Girl 1: "Did you see there was, like, a boy in the girls toilets? And he wasn't young. He wasn't, like, a man, but he was old, about 11 or something."
Girl 2: "11! That's too old. Boys shouldn't be allowed to do that."
Girl 1: "Yeah, I know. Cos boys, they, like, um, smell and stuff."
Girl 2: "Yeah. My brother's a boy and he smells."
I had to stick my head under the desk I was laughing so hard.
