The ones I can't figure out are the tools or parts you are using to do a job. You lay it right down beside you, do the next step, and when you reach down it is nowhere to be found !

You haven't moved from a 3 foot radius and yet it is GONE!
I still can't find the collar to my Chevy preluber. I prelubed the engine, set the whole thing down beside me, and when I went to put it away the collar was gone, never to be seen again.

I've looked everywhere, even under tool boxes, but it's just gone. Gremlins I tell you, gremlins.

That is terrible, sad to hear about him.
