Why would anyone hoard mail? If he did not want to deliver them, then why didn’t he just throw them out, burn them, or something.

People like that think they can just hide their problem. And once it starts they can't stop themselves. Might be a similar mindset to a hoarder, dunno.

Several of these have popped up over the years. They're rare, but they do happen.
