According to QI, if you look around and constantly say “wallet” out loud, your chances of not overlooking it increase. Can also help with recalling where you last remember seeing/interacting with it.

I once saw a duck steal a wallet out of a woman’s bag and waddle off with it.

The same could have happened to YOU.

Mine once fell out of my pants while I was sitting at my office chair. It ended up perched on the bar that connects the seat back the seat bottom. There is a 3 inch gap between the back and the bottom otherwise. It took me a week to find it, and right before i was about to cancel everything. I only found it because i bumped the chair and it jiggled free.

Have you checked the last place you look yet?

Did you leave it under the hood of a car you were working on?

Are you walking funny … ?

Somewhere special that you’ve never put it before, so you wouldn’t forget where it was

gnomes are holding it ransom until you right the wrong you committed against them

Try the couch cushions

Have you looked in Nature’s Pocket?

Check your laundry. And places where you might set things down when moving laundry around.

I’ve found my wallet is often where I first looked, just covered in other junk so I didn’t see it. Also, if you drive, check the crack between the seat and the door. Hope that helps!

By the shitter?

Did you leave it in your car?

You left it where you put it so you can easily get it when you need it.
