At this point, the postal worker has given up on you. They've called in sick, gone on a 5-day vacation, and have sent an intern to deliver the envelope for them. The intern is currently on the 3rd try, still unable to find your house, and is starting to question the life choices that led them to this moment.
But don't worry, the mailman's intern has a backup plan: they've called their mom, who is a retired librarian, and she's coming over to help with the delivery. After all, if a librarian can't navigate the treacherous terrain of your neighborhood, no one can.
