Realizing that you've moved into a new space overseen by an incapable, wildly inconsiderate landlord is one of the worst realizations to have. You're out there paying all that money to live in a decent enough space, and when something goes wrong, you can't even get your landlord to help you out? No thank you. These dudes found themselves with a landlord who just couldn't seem to get around to replacing their busted mailbox key. So, when the tenant's final day of living in the apartment had arrived, and the landlord was nowhere to be found when it was time for the apartment inspection, the tenant put that house key right in the very mailbox that the landlord hadn't procured the new key for. A simple enough, yet brutally effective petty revenge. Plus, this story's been made all the better by those ridiculous typos.
