In the Bible, in the Book of Exodus, God gave His Ten Commandments and the fifth one is that we should honour our mother and our father. The Bible repeatedly says children should obey their parents.
All authority comes from God. The command for children to honour their parents does not give parents the right to be cruel tyrants over their children. If you don't think something is fair, most of the time you can discuss the issue with your parents and come to a peaceful resolution.
Nevertheless, there are many times when, if your parents tell you to do something, you do it without questioning. Most parents want the best for their children and will thus set out fair rules for the household designed to protect children while giving them a good and happy life at the same time.
God's order, set down in the Bible is that Christ is to be the head of every man. The man is supposed to be the head of his home and the children are to be under the husband and wife, the father and the mother. Many times when children are disrespectful and constantly disobey their parents, this is because this order is not in that home.
A girl needs a good mother to show her what kind of woman she should be and a good father to show her what to look for in a man. (Vice versa if you happen to be a guy reading this.)
Granted, there are parents who for various reasons don't know how to train their children in the way they should go as the Book of Proverbs in the Bible says. If you are living in one of these extreme situations, find a male role model in your community or at your school who acts the way a good husband should, and a woman in your community or at your school who acts like the kind of respectable woman someone would want to be.
