      Many teenagers feel that the most important people in their lives are their friends. They believe that their

family members don't know them as well as their friends do. In large families, it is quite often for brothers

and sisters to fight with each other and then they go to their friends for some ideas.

      It is very important for teenagers to have one good friend or a group of friends. Even when they are not

with their friends, they usually spend a lot of time talking among themselves on the phone. This

communication (交际) is very important in children's growing up, because friends can talk about something,

and these things are difficult to say to their family members.

from meeting their good friends. Have you ever thought of the following questions?

      Who choose your friends? Do you choose your friends or your friends choose you? Have you got a good
