Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds.

In the last few months, we've been startled to discover that our mail has been arriving sometime in the middle of the night. A couple of times I have checked it at nine or ten in the evening, confirmed that it was empty and then found mail in it the next morning. We have three explanations for this.

1. We are sometimes the very first delivery on the mail route, and thus our mail is delivered at roughly 5 in the morning.
   
2. Our mail is being delivered to the wrong house and someone is putting it right in the middle of the night or early morning.
3. Our Mail Carrier is a Vampire!
