Is OTHER wrong in the post ? POST : Obligatory 'didn't happen today', but a few years ago. So some context: it was 9th grade, and I was definitely on the lower end of the popularity totem pole.
After 9th period was almost over, everyone was waiting by the door, waiting for the bell to ring. A girl  (let's call her 'A') calls me over to the back of the room. Her friend (who we'll call 'B') is standing next to her. A asks me if I would want to hang out with B sometime. Believing that it was some sort of a joke (Both of the girls were popular; I had bad relations with some of the popular male student), I figured it was a 'Birds of a Feather' scenario. I reply with something along the lines of 'no thanks, I appreciate the offer', and was promptly saved by the bell. It was never brought up since.

I'm not asking to see if I was an asshole for turning her down. I'm asking to see if I was an asshole for possibly misinterpreting her intentions, assuming that she wasn't serious.
