Many teenagers feel that the most important people in their lives are their friends. They believe that their family members, and in particular( 尤其是) their parents, 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 advice. It is very important for teenagers to have good friends or a circle of friends. Even when they are not with their friends, they usually spend a lot of time talking on the phone. This communication is very important in children's growing up,becausefriends can discuss something difficult to say to their family members.
