My little brother is 12 and I don't believe in hitting kids but I really think that boy just needs his ass beat once.

I can't tolerate the level of disrespect towards my mother. She may not be my favorite person but she is my mother. And it just pisses me off. I wouldn't let anyone talk to my mother the way he does or treat her like this sibling or not.

When he gets mad he's violent. He kicks and hits. My mother has holes all in her walls. He tried to attack his teacher. He's mean to my other siblings. Today we had a little BBQ and because it's so hot my mom has her AC on. My brother came in the house and didn't shut the door. My mom asked him to shut it twice and he ignored her (very clearly could hear her) So she raised her voice the third time I wouldn't even actually say she yelled and he no joke started screaming about how she's to bossy and he hates her AND LUNGED AT HER NECK! and she didn't do anything! Plus he slammed the door shut so hard he dented it! My mom didn't even punish him. She asked him to go to bed and he just said no I don't want to I don't have to listen to you and went on playing!

I'm just so angry that I had to go to my room. What the hell is wrong with him? I'm not for beating kids but my mom's smacked me one time when I was young and I never did that shit again. I don't think I've ever seen my brother punished for anything and I don't understand why because I don't think he would be like this if he was
