31. When should parents let teens make their own decisions?

In present-day society,Parents always pay all attention to the children's growth，which major he should chose?what kind of car he should buy?...parents worry all about their children.Their expect to arrange everything for children.But it may leads to rebellion. Should parents let teens make their own decisions? As for me,parents should let it be,don't influence children too much,don't always expect children to walk on the road built by parents,because every life is unique,can't be a copy of their parents'.Let teens learn to make decisions by themselves,which is good to form a sence of independent.My target is the parents who have troubles to get on with teens,they don't know how to deal with the preblems about teens' growth and worried too much.
