According to the speaker, who is most likely to become a victim of pickpockets
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 modern ways; that they are eager to control and dominate; that they do not trust their children to deal with crises; that they talk too much about certain problems -- and they have no 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 entertainment and music. This is not their motives. They feel isolated from the adult world into which they have not yet been accepted. So they create a culture and society of their own. Then, it turns out that their music or entertainment irritates their parents. This gives them additional joy. Sometimes you are resistant, and proud because you don’t want your parents to approve of what you do. If they do approve, it looks as if you are opposed to your own group. But in that case, you are assuming that you are loser: you can’t win but at least you can keep your honor. This is negative way of looking at things. It is natural enough after long years of childhood, when you are 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, so that they will give you the authority to do what you want to do. Teenagers tend to have strange clothes and hairstyles because they ______.
A website is a channel through which companies can promote their products and compete ______.
