Lots of mysterious ones, everybody!
Mine is not a great mysterious picture but is about how I unintentionally created a mystery to my neighbors using mystery money. Took it on March 31 this year using google pixel 3.
I found a ziploc bag with 20-something USD inside in front of my house. I didn't want to steal it, so I taped it to my garage door facing the street. That was ugly and hard to miss, if a kid dropped his/her charity money or something like that, that person would certainly recognize and take it, I thought. I posted the image to a local facebook group and waited.
Two weeks have passed without any taker. When I went out to check my mail box, one of the neighbors came out and asked me "Hey, what did you tape there, it's money isn't it? What's that about?" She sounded really curious but I saw a bit of seriousness in her eyes. As soon as I explained, she started laughing. She said she and her husband have been wondering for a long time if that was some "charm for good luck" or some such. Probably they thought that we were trying to repel COVID by Japanese voodoo.
In the third week I gave up and gave that money to charity.
