Concerningmoney or anything else, conflicts between husband and wife usually reflect a power struggle. Conflicts between parent and child often center around the same issue. As children enter adolescence, they begin to demand greater freedom to go where they please, do what they please，and make decisions without parental interference. Many American parents do not know how to deal with their teenagers and seek advice from books, lectures, and parent training courses.

But quar rels may also concern school work, after school jobs, decisions, use of the family car, dating, and sex behavior. Some families have serious problems with teenagers who drop out of school, run away from home, or use illegal drugs. Because so much publicity is given to the problem teenager, one gets the impression that all teenagers are troublemakers.

In fact, recent studies show that the “generation gap” is narrowing. The vast majority of teenagers share most of their parents，values and ideas. Many parents feel that they get along with their adolescents quite well.
