Retrace your steps, do not rush and makesure you think about everything you did at each place you stopped.

I have found things in the refrigerator before now, putting something down inside, to pick something else up...

I lost my wedding ring a few months ago, and, after doing a walk back, I realized it came off when I put the insert pad on my horses winter turnout blanket... there it was down in the blanket by his tail.

It was cold and my finger shrunk - did not even feel it fall off!

Talk about relief... 😁
