why?

…Teacher man knew I was co-operative with my teachers, that this C.A., liked to pick on and tease me… so he used those factors to get rid of that particular student. He came to me and told me any time C did anything that bothered me to tell him. Well, I did. And it wasn't until C.A. was expelled, that I discovered the teacher was using my complaints to suspend and eventually expell him. (a plot I paid for socially, later on)
