著名主持人杨澜曾说过这样一段话：“这世上到底由什么来决定我们是谁？我认为大概有三件事：完成的事——世人以此来估量我们的成就与价值；不做的事——后人以此来评价我们的操守与底线；想做却没有做成的事——这常常是我们自己才最了解、最在乎的事，是一个更真实的自我的认定。正如设计师的空中楼阁……”

阅读下面短文, 按任务写作的要求以约30个词概括文章的主要内容。
Teenagers’ secrets should be kept to themselves and no one else, their parents included, has the right to stick their nose into their private life.
As we know, teenagers are going through a special period of development both physically and psychologically（心理上). They are curious about and puzzled by the unexpected changes in their body and mind. What’s more, exposed to a world of adults, it is only too natural for them to begin following the example of adults’ behaviors in secret. Boys begin to smoke and girls begin to spend time doing their hair and care more about what to wear. Some even begin to date with a girlfriend or boyfriend without letting their parents know. They are doing all this in secret because they are still unsure whether it is right to do so and afraid that, if found out by their parent, they will get misunderstood and even punished. In fact, in many cases, parents can not deal with such matters well but hurt their children’s feelings badly, making children unwilling to communicate with them any more. When this happens, it terribly hurts feelings of the family as well.
Therefore, it sounds reasonable and acceptable that teenagers should keep their secrets to themselves instead of sharing them with their parents, who should give them the freedom in dealing with secrets.
