I think I have done the thing that I always roll my eyes at when other people do it. I think I forgot to save the document before closing it down.
I was certain I'd saved it on my personal machine, not the network. I have rummaged through the temporary files on my machine. I have even put a call in to IT and risked looking like an utter fool in the eyes of the geeks.
To no avail.
I just have to accept that I have lost it and move on. Hopefully at some point I will be able to recapture those lost thoughts. Who knows, I may write something better. But for now only one word sums up the frustration I feel.
