Another time this girl in an elevator says "Hello" to me, and I say it back, and she tells me she likes my clothes, which I hear a lot, so I'm on autopilot "Thanks you look nice too", and then we part ways. Nothing else said. Don't even know her name.
I run into her during a night out months later and remember her, but this time she's got a whole attitude. So I ask "What's going on here? What's the problem?" and she's all "You don't remember rejecting me before?" and I'm like "Was I supposed to **** you because you said hello? If I tried to climb on top of everyone that was cordial to me I'd never be done"
We worked it out though
