I’ve written the last couple of paragraphs of my story. Read them here: Andrew's Story. Final paragraphs.
I don’t know exactly where to place them in the text, but that’s my next job. And then I’m finished, more or less.
Looking at the final bit I’ve reworked it to replace the twins idea, which was just a bit too peculiar for its own good I think. Apart from that it’s substantially the same.
