The teacher is always against me, just because I once went back without endorsement, and later called my parents to say it, and then I have been against me, damn it.

In fact, every disobedient student will have a misunderstanding: he is always targeted by the teacher. If you don't often do wrong things, be good. The teacher has no resentment against you. Why should he take it out on you?

As for what you said, it is normal to call parents. Teachers have the responsibility and obligation to know about your study. Asking the guardian for information is the most direct and quickest. It's also what teachers need to do. Let your parents watch you, so you don't have to mind.

As long as you study hard and do the tasks assigned by the teacher well, I believe the teacher will not only treat you with special respect, but also respect you all the time and praise you, right?
