Respect has no substitute

Respect has no substitute; neither assistance nor obedience nor love can supply it or take its place It may happen that children are no longer obliged to help their parents; they may be justified in not obeying them; the circumstances may be such that they no longer have love or affection for them; but respect can never be wanting without serious guilt. The reason is simple: because it is due in justice, because it is founded on natural rights that can never be forfeited, even when parents themselves lose the sense of their own dignity.
