Let's see. The worst one about me was started by my English Teacher when I was a senior in high school.
The reason why is a very long and drawn out story that took place from August to May of my senior year that resulted in a lot of drama with her (she was also our speech and debate team coach -- this is why there was drama), our two assistant coaches (men -- ages 24 and 28) and my three best friends (the other captains of the team).
Basically, the team fell apart around her and she didn't want to blame it on herself so she fired our two assistant coaches (who did 99.5% of the work) and then exiled us pretty much (and we were state qualifiers in debate, so we know how to argue and be persuasive, so not smart on her part

).
It truly is long and drawn out and takes me nearly 45 minutes to tell in person about all the events that happened that year.
To make things short, after she fired the assistant coaches, she told the administration at my school that I was sleeping with the 24 year old. This got me in trouble for the fact I was 17, he was 24 and it was almost like student-teacher relations. The problem is, I wasn't sleeping with him and he had a girlfriend. We were just great friends, as I had known him since I was 6 years old, and I was the one who gave my teacher his number to come help out with the team.
I'm still frustrated to this day.
