The parent has the right to forbid. We note that at the same time the parent has no right to demand the child marry whom he or she picks for that child. The child has also a right to say no to the parent's candidate and a right to argue for his or her choice. Here are conflicting rights. So too in the case of the man's right to press his suit.
