I really hate my principal.
Why do you hate your principal?
He's so strict compared to the other teachers, he's always pulls me off for being sometimes late.
I understand your anger, but it's not nice to hate people. You should learn to try and get along with all authority figures.
I don't have to listen to people, who are wrong. If I have a different opinion to the principal, I should have the right to say whatever.
Even of you do not like them, it is wise to find a away to coexist with them so that school is easier for you.
