Do parents need to verify university leave?

Strictly speaking, you don't have to contact your parents when you take leave from college. For example, if you encounter some unexpected situations, such as you are sick, you have an accident and you have to go out for an exam, then you don't need to contact your parents in these situations, just explain the situation to the counselor. But at the same time, if you want to take a long vacation, you need to contact your parents in this case.
