Places I have found mine (and for why I now have about 10 pairs from the 99 cents store in every room of my house):
In the bathroom, in a drawer or cabinet where she was looking for something else and left them.
In the refrigerator or freezer where she left them when the phone rang.
In the garage where she went to get a hammer, then the doorbell rang.
In a different purse or fanny pack, because she switched out purses when she went out to dinner with relatives and didn’t want to lug along her huge backpack where she normally keeps them.
The pocket of a jacket. She put them in there, because she didn’t have the big giant back pack where she normally would put them, because she was out to dinner with relatives a few weeks or days back.
In her car, her friend’s car, her dad’s car. That’s where she left them because she kept taking them on and off when she was reading the map, when she went up north to visit the same relatives whom she had dinner with.
On top of the freezer in the garage. She left them there when she was getting a hot pocket and her mother called her in to see the horrible new news item (earthquake, war etc.)
In the laundry room where she left them, when her nephew called her into the living room to look at his lego creation.
On the upstairs bookshelf where she left them, when she was walking through the hall and the next door neighbor came by with some home made cake.
In the drawer next to her mom’s TV watching chair, because mom thought they were her glasses and put them away instead of leaving them out, because the neighbors were coming over with home made cake.
On the ledge of the bathtub with the curtain pulled because that’s where she left them when she was going to run a hot bath and then another neighbor came by with their itinerary for their trip (they were going on vacation in the morning)
In the closet where the vacuum cleaner is kept, because she was about to vacuum the living room when her dad returned home with a huge bag of cat litter and he needed help brining it into the garage.
On the patio table where she left them when she was putting petunias into pots, but then the smoke detector went off in the kitchen where she was making/burning cookies.
In the TV cabinet or drawer where the remote control is kept. Because she kept putting them on and taking them off while she used 3 different remotes to play her nephew’s Spiderman video so that he would stop whining.
On the next door neighbor’s counter where she went to help the neighbor catch his cat to put him in the cat carrier to take him to the vet for his annual checkup. Or on the neighbor’s washing machine for the same reason. Or on the neighbor’s bed or couch or dining room table for the same reason. Or the neighbor’s bathroom counter where she went after the cat scratched her and she had to get a bandaid for the same reason.
