They hold grudges.

U would think she would have moved on buy now

karma Bad memories last longer than good memories.

Well, I'm the same as OP's girl. There was a kid in my elementary who was pretty much a bully to me as a 4th and 5th grader. He was also a jerk in middle school to those not in "the popular circle." (AKA Kids that all lived by each other.) We were both in Gifted, so we were in the same classes 'til Highschool. For my sanity, I came to accept all of his bull and let him do what he wanted without argument as if it didn't bother me. Come Senior year of Highschool, we end up in 2 of the same classes. Disturbingly, he comes up like a nice guy and talks to me as if we're friends or something. Unlike OP, I was too used to going-with-the-flow of stuff to outright ignore him or be rude, but every time he came near me the grudge bubbled up and all I could remember was all the bad things he ever did.

The comments on fml are too nice

thug life! lol

Karma is a bitch and works in weird ways

People who dwell on things to that extent is creepy anyways

She has every right not to like you! You did something rude. No offense OP.

Well that pretty much sums up your denied slip 0.0
