Forgive and forget.

flip him the bird it's the only thing teenagers understand

Sorry you have to experience such pain we birth them and it's like what's wrong with the youth we teach them respect and all that good things but as soon as they become a teen they forget who they are and try to be something that we didn't want them to be trust me next time return the favor when he needs help pretend you don't know him see how he likes it I know that's hard but they will only know how you dealt if they go through it

Once they're 18 they are own their own and make their own decisions whether good or bad 🤔🤫🤭🥱
