Given that our great leader has recently managed to leave behind his daughter whilst out not drinking much in a pub, I pondered over what I have ever left behind apart from a mess on the table. I left a coat in a pub in Farnborough before a football match that I recovered afterwards and I left an old phone somewhere in Cheshire that wasn't a great loss but other than that I think I'm quite clued up about retaining possessions. I'm sure there are a few nightmare stories out there though!
