Why do teenagers disappoint their parents?

Response:
Teenagers by definition are going through a process of maturation and individuation. They are finding their true self, distinct from their parents who have been their role model since infancy. Part of this process requires pushing boundaries set by parents. Parents often interpret this as disobedience and are disappointed. In fact teenagers who seem to be disappointing their parents are merely going through the healthy process of self identification.
