Traveling with my date, but my mother won't let me go ... what should I do? Will my date get angry if I tell her now?

There is no way for this kind of thing. After all, your mother is doing it for your own good, but you can't always impose the definition of this good word on your children. Everyone is an individual. What should you do if your parents finally leave you? Sometimes, even if my parents are kind to you, I think I should go out for a walk while I am young. Even if you come back from a trip, how can your parents deny you?
