Hell Is for Mailmen

"I don't know which I found more surprising about the afterlife; that it has a mailman, or that I was it."
A man wakes up in a barren '50s-styled subdivision, to discover he is, by all evidence, its mailman. As he delivers letters to empty houses he wonders what this is; why this job?
Until he finds something at 320 Sycamore that changes everything.
