"Do you really think now that you have become the kind of father you should be? Did you forget what you did before? Every mistake you've ever made, every hurt you caused others, can you truly pretend it never happened? Even if you could, I can't accept it. If it were my child, whom I raised myself, I have the right to tell him what to do, I have the right to guide his actions. You never deeply intervened in his life. You're not a perfect father, nor a competent one; you neither have the right nor the qualification.
