When a child marries, he or she is now in charge of his or her own life, with the spouse’s input. Kids will not always do what we want, but what we want may not always be what they need.
The WAY in which advice is conveyed is crucial. We did not want our parents to tell us how to run our lives when we became adults, and neither do our children. OTOH, kids who want to be independent, should not be expecting handouts from parents every two minutes.
I like Artchill’s approach.
