How many more times will the #USPS bring us mail for previous occupants, on which I've written "Not at this address" and deposited into a blue USPS drop box?
Should I be writing something else, besides the above or "Return To Sender" (my second attempt)?
During the holidays, did we not tip the mail carrier enough?
Have I angered some unknown mail god in some way? How can I appease its wrath?
Most importantly: if this mail comes back a third time, do I then get to open it and keep what's inside?
