Mine happened this past year in the college mailroom. I ordered a pack of diapers on amazon, just as I've done many times in the past without issue. A week went by and I received a notification that my package was in, I was so excited since it had been a few months since I had indulged! I rushed down to the campus mailroom and signed for my package.
The girl shuffles around for the package and pulls out a huge case that was labeled in big letters "Goodnites". The company had accidentally sent a pack of 4! I got nervous and asked her if they could keep them there for a bit and that my friends had pulled a mean prank on me. She told me no and I took the package and ran to the bathroom where I ripped open the box and filled up my backpack with the individual packages.
luckily nobody noticed and I got an extra 36 diapers for free! Moral of the story is expect the unexpected.
Equally embarassing was my freshman year of college where I came into my room and, not seeing my roommate sleeping, turned on the lights and opened my backpack up to put two unused diapers away. Once I had them right in the open I noticed him looking at me. I freaked and hid them in my bed, left the room and got baked with my buddies lol. It was awkward, especially since it was a girls diaper but he never said anything about it.
