Thanks Livingston.

It has made the waiting for further episodes of Dave's naration more bearable - and I think I have just thought of a resolution of the plot..

Did I just claim to have a 'plot'?

I can now reveal I did not have one, was just sort of free wheeling along putting in whatever came to mind.

I think I can round it off though with what I have already written. I'll just read through and check that everything is coherent.
