He may be mean, but if he's Joe's neighbor, he's also rich - and rich people have lawyers. So either he knowingly didn't call his lawyer because he didn't care if the restraining order went through and didn't want to deal with it, or he's not "all there" mentally anymore and he doesn't understand what's going on, as you said. Still, you'd hope if that were the case he'd have people around him who could help him.

Strange indeed.
