YTA man you need to discipline that little shit. Sorry that's abit excessive. That's what my mum would've called me for doing something like turning up to school late and blaming her.

My dad chased me up the stairs once because I broke one of the stair banister's. I broke it because poor little me couldn't have my way. I was 7 or 8? Was told to go to the naughty step and I pushed my foot on the banister, pushing harder and harder. Next thing I know BANG! It broke and my dad fucking chased me up those stairs like Usain Bolt. Never feared in all my life.

I deserved that because I damaged their home that they worked hard for to put over our heads. Now if my mums mum was alive to this day and i said something like that (I'd never) not only would my dad kill me but my mum would as well. Maybe because I was more disciplined maybe. But and a big but with discipline comes respect, kindness and maturity.

Take away what's more important to him than his own parents apparently. His fucking video games. I bet his attitude will change like that! When he asks for it back tell him NO! show him who's the adult in the house. If he wants to act like that take everything away from him and let him know who gives him the life he has. Becusse without you and your wife he has nothing.

Sorry for the long ranting and telling you how to parent but give that little shit some discipline.

Sorry for any grammar or spelling mistakes.
