I will say that one time I had a pretty brutal substitute. I'm left handed and do my check marks backwards and she told me I had to do them the 'right' way. I told her no and she was like ya and I was like naww and it ended there.
She also tore a kids paper up for not underlining his title twice.. he cried, she sent him in the hall.
I guess that was pretty nuts.
But still man, why do people hate teachers, sure some people power trip, I mean fuck the police right, but hating for the sake of hating is lamezoids
