I have solved this mystery already, so you don't need to give me advice. However, I want to tell a story and I'll let you guys guess what actually happened. I have told a few of you personally, so if you already know the answer, please don't spoil it.
Yesterday I did two things which required showing my ID. The first was that I got a new iPhone. The second was that I picked up a prescription which required ID.
Coincidentally, right after I got home, I needed to get out my ID for a web form I was filling out. I brought my wallet over to the couch, and opened it. To my horror, the ID was gone!
My old ID (the same one with the same number, but expired in 2017) was still in my wallet. I actually carry that around just in case I lose my current ID, like what happened here. Anyway, the old one was there, the current one was gone.
My wallet has an ID compartment where it's hard for things to just slip out. So I was really perplexed what happened. I was fairly certain the pharmacy didn't give it back to me. Why? Because that was the very last thing I did before going home. I went to the cell phone place first, showed ID, bought it, then went to the pharmacy, and showed my ID moments before being handed the prescription. Then I walked out and went home. I stopped nowhere else along the way.
I went back to the pharmacy and they checked the camera for me. While it was semi-blurry, it seemed as if I was indeed handed back the ID, and the camera also seemed to show me putting it back in my wallet, and putting the wallet in my pocket. It did not apppear that anything fell on the ground, but again, it was a bit blurry so hard to be sure. I didn't see this footage (they couldn't show me due to "policy"), but the person telling me seemed sincere and I got the vibe that they legit felt bad for me and wanted to help.
I also went to the cell phone place, just in case. They checked the cameras also, and said that they couldn't see that well either, but again it seemed I put the ID back in my wallet, and the wallet back in my pocket.
Neither place found any ID lying around.
At first I was convinced it had to be the pharmacy where it vanished, because I did show them (successfully) an ID to get that prescription. However, then I had another thought: What if I lost the ID beforehand -- maybe at the cell store, maybe even days or weeks ago -- and the pharmacy accidentally accepted my old ID as valid, since their computer system would indeed show I have a valid license (and it's the same # as the new one)?
In fact, I remembered that on Halloween, I took just my ID to walk with Ben around the neighborhood, and I wasn't 100% sure I put it back. I checked my pants from that day (I hadn't washed them yet), but no ID. But did I lose in on the street somewhere?
I have since solved the mystery. I'll let you guess where it was.
