As a result, many parents complain

As a result, many parents complain that teenagers are becoming too
individualistic and too isolated from the family. On the other hand, teenagers think that parents should respect their privacy. Psychologists
say that if the teens lock their bedroom door, parents should just keep
on knocking. Parents have the right to know who their sons and
daughters are with and what they are doing. But parents must be
flexible, too. Some parents are very strict and try to keep control of
their kids. But in the end, that doesn’t work, because it makes teens
rebellious and unhappy. The more unhappy teenagers are, the more they
want to be left alone. Some may even turn to the Internet and give up all
social encounters with family members and live in cyberspace.
