Never lose your phone. More than that, I am tempted to say, never buy one in the first place.

Two weeks ago, at a motorway service area far, far away, probably somewhere in the Vendée, I left my smartphone on top of a rubbish bin while I disposed of the packaging and remains of what passed for my lunch. Only the following day, back home in Brittany, did I realise the catastrophic nature of my misfortune.
