Expectations

Parents have expectations of their children with everything from grades in school and how they dress to college and career choices later on.

Parental disappointment creates conflict and problems in the relationship between them and their teenagers.

It often comes across as anger, giving teenagers the feeling of rejection from the people who were once the most important figures in their lives.
