     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 can only 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 them on the phone. This communication is
