Until he can be regarded as an adult, there can be no mention of your responsibilities to him, only his responsibilities to himself.If you really want to make him obey, let him be completely free, hide yourself, and he will come looking for you.Talk only about what he cares about, and in this way arouse in him a noble attitude of gratitude.I don't want you to tell him that everything you do is for his own good before he can understand.Such words can only make him understand that you depend on him, and he treats you like a servant.
