"You can be really dirty sometimes."
"Yeah, 'course I can. Everyone can be."
"You've got a long-term boyfriend," I pointed out. "You've probably got a lot more experience than the rest of us."
At which point I stopped saying anything. Lightsinthesky had just walked in and I certainly didn't want to hear about how much experience he had.
"Yeah. I'm probably going to marry him, too."
Unlike some of the other upper-sixth-formers taking more ASs, she was less of an enigma. In bigger AS classes, we usually had one or two - older ones, usually girls, taking on a different subject in order to get another qualification. In our English class, we had one I never really talked to, because I couldn't remember her name. For a while, I thought it might be Urethra. This one, however, was in our Philosophy class, which consisted of five. We were a tight unit - me, Lightsinthesky, two smart girls who we got on well with, and her. She was part of us, and when she'd left in our second year, we generally felt bereft.
She was, of course, incredibly good-looking. Lightsinthesky looked upon her with barely-disguised lust. I just thought she was a nice girl... with her dirty moments.
Lightsinthesky had entered the room with one of the other members of the class - the one who decided she'd evolved from a sheep rather than a hominid, and ended up getting straight As in her A2s.
"No, hang on, it's got to be three."
"I thought it was three."
"My mum told me it was two?"
"Your mum's wrong."
"Mums are never wrong."
"Hold up, hold up, hold up, hold up, hold up, hold up, hold up, hold up, hold up, hold up, hold up, hold up, hold up, hold up, hold up," I said, although I probably didn't say that. "What's all this, then?" Only I probably sounded less like a policeman. I think I probably said something like, "Huh?". Or maybe I didn't say anything at all.
"How many holes does a girl have?" he asked. "I thought it was three, but she says it's two."
"I think it's three," I said.
"But she's a girl, so she should know."
"No, it's three," our upper sixth colleague pointed out. One here..."
...at which she pointed...
"...and one here."
All with a dazzling smile.
"Hey, guys, what are you talking about?" asked our teacher as she bustled in with what looked like the Dead Sea Scrolls cradled in her arms.
"How many..." started Lightsinthesky, before I trod on his foot and he stopped talking.
"It's fine," I said, "it's a question that's been answered." And I sat down, got out my books, and made a mental note to have a word with the Biology department.
