Why? Tell me exactly why it's wrong that I know better? I'm mentally am adult, and can make my own choices. You don't seem to understand that I respect their authority, and I do what they say, but I ultimately know more than they do.

The problem right now is that you think you know better. What's wrong is thinking that you know better, even though you don't. Not yet. Not as long as you are still part of their household, because God gives them the wisdom to train you up in the way you should go. Once you really are an adult, that wisdom becomes yours.
