Some people think only school children do not agree with their parents, in fact, it is not true.

Communication is a big problem for parents and children of all ages. If it’s hard for you to communicate well with your parents, don’t worry about it. Here are some advice for you to bridge the generation gap.

Don’t argue with your parents. Don’t get to your parents when you are angry. On one hand, your parents probably won’t consider your ideas if you are shouting at them. On the other hand, you can’t express yourself well if you are angry. Please go someplace to cool off, try to make sure you understand why you are unhappy. Then, think about what you want to say to your parents. If you don’t think you can speak to them at the moment, writing a letter may be a good way to help you.

Try to reach an agreement. Perhaps you and your parents disagree on something. You can keep your disagreement and try your best to accept each other. For example, Michael wanted to buy a motorcycle, but his mother didn’t agree with him, they argued over it. Finally, they came to an agreement. Michael bought the motorcycle, but he could only drive it on certain days.

Of course, your parents might refuse to agree on something. In these situations, it is especially important to show your love and respect to them. Showing respect will keep your relationship strong.

Talk about your values. Because of the generation gap, the values of your parents are probably different from those of your own. Tell your parents what you care about, and why. Understanding your values might help them see your purposes in life.

A good relationship with your parents can make you a better and happier person. It is worth having a try! Communication is an art!
