why he keep coming back if its childish and he outgrown it?.
Because this is the pinnacle of his existence. This is all he has. The only interaction he can get with people outside of his bedroom. He gets to sideline commentate like he was born to do, and watch a bunch of n*ggas he will never meet post MATERIAL sh*t he wish he could buy. Just a bunch of clothes and shoes. Some sh*t to some of us lucky enough, to have some extra funds that we worked hard for, to drop on ourselves. But not him. He will never know that feeling. He will never know how it feels to be great either.
He is the exact definition of what Struggle is. But not a beautiful struggle. The one where he won't do no better, because his father was a chump, so this lil sh*t don't know now better.
I can only pray your lil brother uses you for an example of what not to be.
