     It is Saturday afternoon. You and your friends are planning to go to the movies and then spend the night

together. Just as you start to get ready, your dad reminds you that it is your aunt's birthday and the whole

family is going out to dinner to celebrate. How can this possibly end without a huge argument?   

     One of the greatest sources of tension (紧张情绪) between teenagers and their families is the struggle

to balance personal desires with family expectations. As you are getting older, you are becoming more

independent and more interested in being with your friends.   

     However, at the same time, your family is trying to figure out how to deal with these changes. While

you once spent most of your free time with your family, you are now often absent from home. Parents

may get their feelings hurt. Or they might feel that they are losing control of their family during this period.

You might feel angry that so many family demands are placed on you.   

     There are a few things you can try to make it a little easier to ease (缓解) the tension.   

     * Make your plans in advance. Ask your parents if there is anything else planned at that time.   

     * When something with your friends interferes (冲突) with a family event,try to figure out if there is

any way you can do both.   

     * Suggest something you would really like to do with your family. Sometimes parents feel better just

knowing their teenager wants to spend time with them.   

      Some of the time you won't be happy with the outcome (结果). You might either have to disappoint

your parents or have to miss out being with your friends. However, if you show consideration for the

feelings of both your family and your friends,you can solve the problem in a tender way.
