He is your uncle and his name is Albert. Your father asked him to sit with you for a while, because you have a disability and cannot move your legs. You are 9 years old, and therefore you do not know how to do some things yourself. Albert is very annoyed by this, because instead of sitting with you, he wanted to just play the console. Therefore, he decided that if he killed you, then he would no longer need to look after you... He is a mentally unstable adult. He walked up to you and suddenly grabbed your head, forcing you to get up from your wheelchair. He heard you start to say something. Shut up, kid...
