My little brother vomited because I shook him so much.
That's not good, what would make you shake him like that?
Because he was being a pain.
It's horrible to shake your siblings. You could really hurt your brother.
My parents hated him and sent him to live with my grandmother for awhile. I think that he deserves all the pain in the world.
It makes me sad to learn that your brother is being treated harmfully and with such disdain. You shouldn't shake him, regardless of your feelings, and you should be more mindful of his feelings and wellbeing. It sounds like he is experiencing many negative things in his life.
