My class teacher was giving everyone library card . But when it was my turn to get it , he gave me it , but quickly snatched it and started saying that you need to show the record that you have returned the book and we can know if a library card is genuine or not (while doing evil smirks) . Another time , I was helping in packing of gifts and decoration in a function , he came running (literally) to monitor if I am stealing gifts or not . Why this POS treats me like I will steal something , he doesn't do things like this to others or anyone . I never had any history of stealing . BUT I do come from comparative lower economic class . He intentionally does this , he get pleasure out of this . POS ! Should I take revenge ? Should I get no contact with him ? Leave school early ? Don't attend school functions ? Like farewell etc .
