Call it hubris. Call it comeuppance. Call it the little man on the back of the Emperor's chariot saying 'You are only human'. Whatever you call it, it happened.
After crowing about last week's word output, I'd been working for about three hours today when my Mac ate my entire 51,000 word book. Hit save, it hangs up, then it crashes. Pages has had a failure and been forced to close. Mostly, you lose a couple of pars. This time Pfffft and the file disappears from the desktop. Search all you like, but it is no more. This is the second time, but I'd learned my lesson and I'd backed up my backups and most of my work was saved.
Suffice to say, I didn't do quite as much today as I expected.
We have a saying in the Borders: What's for ee, u'll no miss ee. Next time I'll keep quiet!
