Is that supposed to make me more or less depressed about humanity? I'm having trouble deciding.
I think the Post Office actually has rules for what to do when they get letters addressed to fictional people and addresses. They have to have rules - think of how many letters they get "to Santa" every year.
I guess they also have a procedure in place for when a kid writes to God asking about a dead pet.
When I think of it this way, the story sounds really macabre and depressing.
