Adolescents are not monsters. They are just people trying to learn how to make it among the adults in the world, who are probably not so sure themselves.
Every word, facial expression, gesture, or action on the part of a parent gives the child some message about self-worth. It is sad that so many parents don't realize what messages they are sending.
Feelings of worth can flourish only in an atmosphere where individual differences are appreciated, mistakes are tolerated, communication is open, and rules are flexible - the kind of atmosphere that is found in a nurturing family.
