There is a tendency among children, even as adults, to blame Mom and Dad (especially Mom) for all the things wrong in their lives. What adult children often forget is that the way they treat their mothers is the example they are giving their children for how to treat them later.
So the question is.....How do you want your children to treat you when they are grown up and leave home? Will they blame you? Will they ignore you? Will they return your phone calls? Will they invite you over? Treating parents with love and respect is no guarantee that your children will treat you that way, but it sure increases the chances. Besides, it also keeps the 4th Commandment.
