I work out of town and travel a lot. One morning after arriving home late the night before, I couldn't find my wallet. I searched everywhere, including the truck, and all my dirty clothes, and it wasn't to be found. Obviously I had lost it when getting gas or something in my travels.
I had to cancel all my credit cards, company credit cards, get another drivers license, CHP, etc, it was a real pain. To make myself feel better I got another wallet just like the one I had, since I liked it so much.
About a week later I'm in the utility room, throwing out some plastic trash bags next to the dryer that I had brought dirty laundry home in, and there was my new wallet laying on the floor. How in the heck did that get there I thought, as I took it to my nightstand only to discover it's twin already laying there.
On the bright side the newly found "old" wallet still had the $350 travel cash in it that I thought was lost forever.
My father suffered from severe memory problems in the last years of his life. I had many meetings with doctors as they diagnosed and talked to us about which parts of his memory were being affected.
The doctor told me that forgetting where you left your glasses doesn't mean you have memory problems, it is perfectly normal. But forgetting that you wear glasses, now that is a different issue entirely.
