Relationships between parents and children are complex. When we are young we take for granted everything that is done for us. We don't appreciate what our parents do, rather we expect it. When we reach adolescence, not only do we not appreciate our parents' role, rather we are in open rebellion at them and everything that they stand for. It is only as adults when we realize the extent of the complex choices that our parents made do we begin to feel gratitude to our parents.
