I'll bet you never parked your car in the huge parking lot at one entrance to the oversized store, only to leave the store by the Other exit. I did it again yesterday. Too much on my mind, I guess.
SO -- No car where it should be! At least it's not where I thought it should be. A friendly shopper offered assistance, but there was no car anywhere that it "should have been".
Finally the light dawned - Ah ha ! I had parked near the entrance I used to go IN.. not come Out. Retrace steps - inside the building, not in the drizzley rain - to the other end of the world. Well, it felt like the other end of the world, as I trudged along, but it was only the other end of the store.
Sure enough, there's my car, sitting where I left it.
In the 'old days', we tied a yellow ribbon or something to the radio antenna, for easy locating a parked car. No more, with built-in antenna.
I toyed with the idea of using the emergency signal on my remote... but I absolutely hate cars that do that---sit with horns blowing constantly until someone wakes up and clicks the signal again to turn it off.
By the time I located the vehicle again, rain was really beginning to come down. The run in for a couple of items had turned into a length trip after all.
