The role of a good son or daughter changes over the years. Initially, being an obedient child is probably all that a parent requires. But when a child grows up and begins to become independent, then a good son or daughter is a person who has good character—who does well in school or succeeds in a career and demonstrates the personal qualities that the parents have tried to teach. Um . . . a good son or daughter is also a good parent when they have children of their own. When parents see their grandchildren being brought up well, uh, they know that they have provided a good example. And . . . and when the parents become old and need care, a good son or daughter won’t be too busy to spend time with them and provide them with help.
