Just as an aside I can tell you about a girl up here who didn't wear knickers either.
Some years ago I was chatting to the girl behind the counter in the local newsagent, she'd just had her hair bleached and I asked what her real hair colour was.
Bugger me days, she had a quick look around the shop and then pulled her skirt down and showed me her snatch. It was brown haired and quite nice looking. There was an opening there for a bloke if he'd been quicker. I must be an appealing kind of dude.
