omg, when i was in 7th grade, my geography teacher left on maternity leave at the end of the first semester and we had the bitchiest sub to fill in for her, and then my teacher decided that she was gonna quit while we were on xmas break, so the sub took the fulltime position for the rest of that year, oh god it was awful
I had the opposite happen.
Got into a math class, had the most awesome teacher ever, thought she was the full time teacher till friend told me that it was only a sub.
then
she came back....
but my story ends on a happy note since 99% of the time we made her life a living hell in the form of stink bombs (we stuck like 9 in her desk once, set them all off at once) stealing her *** (I think we stole her purse once and tossed it on the roof?) um.... some kid would shoot rubber bands at her (think she got a few in the eye once) and we can't forget the thumb tacks on the seat, he stuck like 30+ on her chair :p
we were not nice to this teacher :x
