Sometime WAY long ago in the last century . . . my first ever flight, when paper tickets were the only ticket . . . I had been entrusted with it (after heaps of persuasion by irresponsible 16 yr old BB, my mother gave in). We were half way to the airport when I realised that beautiful ticket I had been admiring at length, was still at home..!!!
It fortunately turned out fine, with just enough time spare to turn around to retrieve it, but I have been paranoid ever since about leaving important documents at home.
Plead guilty to having left passport on plane on arrival though, and then having to get the assistance of staff to retrieve it
and that was following an episode where I had left my laptop on a plane and that was following an episode where I left my glasses on a plane . . . oh dear, a bit sad really
but as things happen in 3's it's been all good since then.
Dearest but quite elderly friends of ours were off on their dream cruise on the QM2, and were distraught as discovered on day prior to departure they could not find passports. Mr BB was there helping search, I was on the phone from other side of the country trying to come up with brilliant suggestions of where to look . . . all to no avail . . . it wasn't until their daughter came up with a suggestion (whilst on the phone from the UK) to look on top of the fridge..!!! We still can't work out why/how they were there but at least a good ending and they adored their cruise.
