So true,

Starting to happen to me. One day recently I drove the kid to school. On the way home I stopped at the shop to get breakfast and a newspaper.
Later when it was time to collect my son. I went out, no car in the driveway.

Stolen? No who'd steal that heap of junk? But where the heck was it?
Eventually on a hunch I went to the shop and there it was. Obviously I must have walked home but had no memory of it. If anything I remembered driving home!
