Are you the only child in the family? If so, you are the most important in your family. Parents are the closest people to you in the world. But most middle school students have a problem. They feel they’re not as close to their parents as before.

Some students complain that their parents often say a lot to them, but never listen to them. Some say their parents ask them not to play computer games when other classmates are doing that. Others say when they’re making phone calls to friends, their parents like to ask if the children are speaking to a boy or a girl. These make them very unhappy. Some students even decide to leave home because they’re afraid to tell their parents when they have done something wrong. Then they usually think running away is the only choice. But they don’t know running away may bring them some more problems.

Problems are parts of life. Here are some suggestions for you to solve the problems.

·Find a good time to talk with your parents. Don’t be afraid to tell them your feelings.

·Get help from others like good friends or teachers.

·Keep a diary to help you understand more about yourself and your feelings.

·Show your parents you’re growing up. Then they’ll feel you’re not a small child.

If you follow the advice, you’ll have a happy life and never think of running away.
