I don’t like my parents. They always tell me I should do this, and should not do that. It sometimes makes me angry,” said Liu Dan, a middle school student in Beijing. Do you have the same problem? Perhaps your parents had the same problem when they were your age long ago. Why does it seem that some parents are not so friendly in their children’s eyes?

One of the biggest things is when someone becomes a parent, he or she likes worrying things. They worry about everything about you from the time you were born. They do a lot for you, though something would make you angry, because they care about you and worry about you. They worry about your choice of friends, the food you eat, your work at school, how much sleep you get, etc. All these things are part of your life. They want you to grow up healthily and happily.

So how can you make things easier on yourself? It’s easier than you think. Just make sure your parents know what you’re doing. Get them to know your friends. Call them if you stay somewhere else later than usual. Say sorry to them when you make mistakes. Take responsibility for what you have done. Talk about your ideas with them. They may talk about theirs with you.

Most of all, try to think about why your parents do this or do that. They are still practicing being parents and need help you can give them. Someday, when you become a parent, they may be able to help you how to get on with your children.
