Rural mail delivery is always a crap shoot around here. Mail carriers are always changing and don't stay long enough to learn the route. We frequently get mail addressed to others and just put it in the proper box ourselves. Unfortunately, there is one individual on the route that can't be bothered, and just throws it out. He won't even take the time to write "wrong address" on the envelope and put it back in his box for the mail carrier to sort out. We've lost several important pieces of mail because of this.
It seems wherever you go, there is always a crank like this to deal with.
