I have photographic evidence that I had my eyeglasses 4 days ago, but I’ve looked up and down, inside and out for them to no avail.
This also happened with a SD card reader dongle thing—it was JUST THERE on the table by the couch. Vanished.
Alas, I went to the drawer where I store old specs and found a pair with the closest prescription and let it go, for now.
