Now I'm glad that I'm not the only one. I couldn't count how many times I've gone to get something which hasn't moved in a year or more; only to find that it's missing. I can look in that spot ten times and not find it; then when I replace whatever I've been looking for it will reappear.
At least I've gotten good at helping others find things. My father lost the keys to his pickup, and had to get a ride home for his spare. It bugged the crap out of him, as it was when the Alzheimers was starting to affect his memory. I had a good idea where they were; GM pickup seats have a natural funnel where the seat belt comes out, and anything you drop slides down to the floor. The next time I was visiting I went out to his truck, reached down, and pulled out his keys.
The worst thing I've lost was in 1997. It was a $1650 electronic data collector with three days work on it. I never did find it but suspect that either I left it on my car roof and drove off; or the kleptomaniac dog I had at the time took it off the front seat and left it in the woods.
