I lost my Glasses

Hmmn, I've looked everywhere but they're gone.  Not on the car, not in the closet, not in the pockets of my coat, not hidden under the jumble of newspaper.  Gone.

I know what you are thinking:  All old people "lose" their reading glasses at least once a day.
You think I have just misplaced them, and that they will turn up shortly, when I remember where I left them. 
But no, this time they are really lost. 

I had them yesterday morning when I went out.  I discovered them missing at Home Depot whern I was trying to read the small print on the package I was looking at.  I checked every pocket.  Gone.

The worst thing about it, they were the expensive bifocals that I never take with me if I leave the house.
 The only reason I took them with me is I have lost all of my traveling glasses too.
Where do they end-up, all those glasses??
