Anger of parents
Parents may often act of an anger toward their children that originated outside of the relationship. The parent may be bitter about his or her career, unhappy in a deteriorating marriage, or disappointed with him or herself. Addressing the real causes of the anger can be a huge task even if the parent is aware of them.

So children may be like shock absorbers, convenient outlets for a parent's frustration. Since their young lives are not the real source of the problem, the parental anger never ends. The parent's displays of anger or the efforts their children make to change never solve the real problem.
