Go on, you all wanted to know whether I ever found the spare car key. Of course you did.
Well, I did find the spare key, and now won't be locked out of my car again. It was in the caravan where it should have been, but not in its ordinary place. It was down in a narrow gap in front of the radio/CD player control plate. Quite a good sneaky hiding place really. I don't see how it could have slipped into that gap, so I must have put it there. But I don't remember doing that, and I don't as a rule have 'safe' hiding places for things, because I invariably forget all about them. So it's a real puzzle what I did. And it can't be put down to Dru's amazing damson vodka, either.
At any rate, I won't now have to spend maybe £150 on a new spare key (they contain electronics and have to be 'programmed' at a dealer). Was I relieved!
