He was a good dude at his core, but he had a significant narcotic addiction (understandable). I knew he was strung out when we offered to fix his wheelchair, had it fully paid for, and he kept just asking for the money instead.
Honestly it really bummed me out and made me question my radar.
The rusty comment was my attempt to bring him back to some version of reality. He was engaging in a giant pile on and I was pointing out his glaring hypocrisy. We spoke privately a few months after and he admitted that he was completely out of control at the time... I hope he's still alive and doing better with reality than he was then.
Like I said, I really liked the guy.
