Ooh, ooh, and another one I've just remembered!
Not a flight but before a holiday.
I had recently read the first chapter of Dale Carnegie's "Stop Worrying and Start Living" which advised me to keep my thoughts in 'day tight compartments' and concentrate on the present day.
The next day, I was going on holiday after work with my boyfriend so concentrating on today only I decided to go down the pub that evening. It was a Sunday and this was in the 1990s so I knew I wouldn't be out late.
Unluckily, I crossed paths with a party animal friend and ended up sitting on a bench taking speed with him until the early hours. What japes!
It would have been about 3AM when I made it home. The next morning I peeled myself out of bed at 7AM hungover, on a mad comedown and had to start throwing clothes into a bag for my holiday screaming "this is why we don't keep things in day-tight compartments, Dale!"
Got to work and at lunchtime - the office closed early as we were all going to the funeral of a colleague who had sadly died recently.
Got a lift to the funeral with my friend/colleague who had to stop the car for me to vomit by the side of the road. That was nice because about 3 cars full of my work colleagues then passed me heaving by the side of the road.
Exchanged pleasantries with the Assistant Chief Constable at the graveside (police funeral).
I've got loads of these kind of stories, sadly. I'm ever so straight now though!
