If someone treats you badly, just remember that there is something wrong with them, not you. Normal people don’t go around destroying other human beings
You can’t avoid being treated unfairly by others. Or there are people who treat you badly, even though you have done nothing wrong or affected them.
You should not care about them. When someone behaves improperly with you, it is their fault, not your fault.
Because you are not a bad person to do bad things to them that they can retaliate against you. You have better things to do rather than harm them.
If they are normal people, they will not behave badly to you. Ordinary people do not destroy the lives and personalities of others.
So those who don’t know how to behave are those who have abnormal qualities. Just ignore them and focus on your work. That’s enough.
