When I got my first letter (refusal) and documents back, I had put up like 6 signs letting the UPS guy know we were home and the doorbell wasn't working...I also left the main door open - storm door closed...and just walked around the foyer all day. Then I heard someone so I ran out to see the UPS guy walking away and my package on the front stoop.
It's like he knew. Ha.
But yeah, I don't know why but the UPS guy didn't even get a signature from me!
