It seems there are two phases to this relationship. The relationship changes when you become an adult and leave the home.
First, while living with your parents as a dependent and being cared for by them, you are to be obedient.
Second, when you move out, especially if getting married, you heed the call, "leave your mother and father and cling to your husband/wife." You have a duty at this point to start a new life with your spouse. It would be unfair to require your spouse to adhere to the requirements of your parents. Likewise, you would be irritated to be bound to your spouses parents demands. It is time to cut the apron strings.
There is one catch. You must not humiliate or anger your parents, even after moving out. They deserve total respect. You can disagree and in this way grow together. Frank discourse is in a manner showing them ulitmate respect. It means in some cases, you love them enough to help them.
By the way, I know a real case where parents browbeat their children to be obedient even after they are married off. It is painful to watch.
