last night after the lecture,

she took the little cheese knife and started to slice the pointy part off the wedge of brie in a great triangular chunk.
oh my god! i said, already drunk on the punch. you can't do that. you have to slice it from the side!
i can do whatever the fuck i want, she said.
and i apologized because of course she can (she always does) but i was still annoyed she didn't listen.
