Okay, well, today I was on my only computer, a laptop, and my brother randomly takes my paper jams guitar and slams it against my keyboard, breaking off two keys, the j and m key, I think. One of them had its hinge actually cracked. Well, I told my mother, and now he's pissed, and is using his "I cleaned the kitchen!" As an excuse. This guy always annoys me, and sometimes my mother just says to ignore him, but it's hard. His in-game name is Split Screen, and he's a terrible builder, spams stuff, and is annoying in general. What should I do?
