If you know your position is righteous, you’ve made your point and your opinion is clear, but your child simply won’t accept it, you may have to let him have his way. Let him suffer the consequences, within reason. That’s still not giving up on him. There’s still hope going on there. Suffering consequences can be convincing where nothing else is.

It was not what you wanted to do and it pains you to know that trouble could have been averted, but he (or she) has insisted on his way. If you don’t give up the effort, the more you try, the more he will fight you. Some will fight to extremes you don’t want to go to, and will not give in to you. Some will become a worse person simply to win, so to give up the fight eliminates the conditions for his unrighteousness to become firmly established.
