Now that's FUNNY, and stressful.....
Here is my story...... like 15 years ago I was in a long term relationship and my GF was 100% OK with my hobby.
Naturally I was ordering lots of sexy stuff for both of us. We were both working full time so no one was home for most of the deliveries.
I got in the habit of either ordering and saying, or posting a note on the door. If no answer deliver to the neighbors address.
They were both retired, and we were like family. After a while I started to notice that the bottoms of the packages had been re-sealed.
After I first noticed it, then for me it was sort of a joke / humor that they were that interested in what was going on......
Years later I became even closer with their children, and one day I told their daughter what was going on.
I don't know if she was honest, or just wanted me to feel better but she assured me that her parents never mentioned anything about all the "Queen Size" clothing that kept arriving even long after my GF moved out.
Some times people just don't really care what happens when you close the doors.
Live and let live, if the neighbor guy is wearing a dress, that's a lot better than some of the stuff that's on the news.
Safe to assume the UPS & USPS people are not clueless as to who on their route is doing a steady business of ordering items that might not be car parts......
