It is natural for young people to be critical of their parents at times and to blame them for most of the misunderstandings between them. They have always complained, more or less justly, that their parents are out of touch with modem ways; that they are possessive and dominant; that they do not trust their children to deal with crises; that they talk too much about certain problem—and that they lack sense of humor, at least in parent-child relationships.
I think it is true that parents often underestimate their teenage children and also forget how they themselves felt when young.
Young people often irritate their parents with their choices in clothes and hairstyles, in entertainers and music. This is not their motive. They feel cut off from the adult world into which they have not yet been accepted. So they create a culture and society of their own. Then, if it turns out that their music or entertainers or vocabulary or clothes or hairstyles irritate their parents, this gives them additional enjoyment. They feel they are superior, at least in a small way, and that they are leaders in style and taste.
Sometimes you are resistant and proud because you do not want your parents to approve of what you do. If they approve, it looks as if you are betraying your own age group. But in that case, you are assuming that you are the underdog; you cannot win but at least you keep your honor. This is a passive way of looking at things. It is natural enough after long years of childhood, when you were completely under your parents’ control. But it ignores the fact that you are now beginning to be responsible for yourself.
If you plan to control your life, cooperation can be part of that plan. You can charm others, especially your parents, into doing things the way you want. You can impress others with your sense of responsibility and initiative, so that they will give you the authority to do what you want to do.

A. children’s weakness in dealing with the relationship between them and their parents
B. parents are responsible for the misunderstandings
C. the misunderstandings will also remain in spite of people’s efforts to make improvement
D. children’s complaints about their parents
