George shrugged good-naturedly. "But it is different with blokes than girls." Thus the appeal of liking both. If it was the same, there wasn't much point in liking both. George appreciated nice, soft girl-curves and all that went with them, and the less-soft and not-so-curvy blokes and all that went with them. More girls tended to turn his head, but George mostly thought that was because he hung out with a lot of bloody gorgeous women.
He laughed as Remus snatched the glass and gave him a flipped two fingers. "Quick, Lupin." Which wasn't surprising, since he was a wolf and all.
"You're probably too pissed to get into positions anyway," George answered nonsensically. Since he wasn't quite that drunk, so it was unlikely Remus was. This was an odd sort of conversation to have with a Professor. He half hoped he remembered it tomorrow, just so he could tell Fred about it. Though Fred would probably think he was full of it if he said he half thought Lupin was making a pass.
