I lost the gold ring that I've had almost all my life. Everyone in my family used to have identical rings, but they had all lost theirs, or had them stolen. Owning the last remaining ring had allowed me to annoy them by claiming to be the rightful family head.
So I went to the cop shop in case someone handed it in. The police were very friendly, and when I showed them a photo of the ring, they said it would be helpful if they could have the original file for their database. To reach my USB stick, I unpacked half of my backpack on the counter, including a discarded bail court attendance order that I had found in the street outside.
I warned them that there might be hundreds of photos on the stick, but they said that wasn't a problem. One of the officers plugged my USB stick into his computer and seemed to spend a long time looking at the contents. I suddenly wondered - what the hell else have I got on the stick? Eventually he found the ring pic, and took a copy to file with his report.
When I got home, I checked the stick, and found multiple full frontal photos that Denny and I took of each other, pissed of course.
