I fear for my mind:
Just to keep my car battery charged while the car is in dock I run the engine every now and then. Came to do it this morning couldn't find the keys. Also couldn't find the spare set. Spent half an hour rummaging around, no luck. Was even about to contact my son and accuse him of hiding them.
Odd thing was that I had the fobs. I'd found other keys (what for I've no idea) and went to put them on the key hooks by the back door. I looked at the car keyfob and it was then I realised that the key folded in the fob
Senior moments don't come any better.
