One of the worst things about family relations that young people single out is lack of privacy. They often complain that even if they disappear into their room for some peace, its guaranteed that some one will come after them, wishing to know what they are up to. With parents, brothers or sisters in one house they dont have a chance to be alone, unseen or unheard. Some of them even say that their family members have no sympathy for their feelings. I believe that when families have such problems the first thing to do is to talk. Children must tell parents what makes them unhappy. Calm communication without the words that hurt people, will definitely provide a solution. Teenagers are vulnerable and they need someone to talk to.
