I have just retrieved my 'phone. After taking the car to the garage, a coffee and croissant with MrsP at the coffee shop, and a walk back across the fields with the dog, I realised after a while that I was not in possession of the mobile device.
A short while after, my good friend turned up, after trying unsuccessfully to call me saying '' I know you have lost your 'phone , and I know where it is''
So he drove me to the house where a gentleman had picked it up, and the crisis was over.
Faith in human kind restored all round.
