“I just unplugged a lamp out of anger because I couldn’t figure out how to turn it off.”
Error, I think it is you who doesn't that Fresh has antisocial personality disorder. This means he can't feel at all. You should read the wikihow page on 'How to Understand and Help Sociopaths' it has a section for understanding a person with sociopathology and helping someone with sociopathic tendencies. It might help you understand him a bit more. I just want you to treat Fresh better since he is your brother. He's sick like Geno but in a different way since it is his brain that is sick.
