Thanks John, I thought that would be the case. That can be a terrifying prospect though. I don't know if this is a common trait amongst other writers, but I'm quite paranoid about that. The fear is that there's always some hideous error staring out from the page that's obvious to everyone else but me.
It seems that each time I look through a draft, I'll find something in there that isn't quite right, and I often wonder if there's ever a point where you can truly reach a moment of real satisfaction - I suspect not! Or is that just me?
It's a good job I enjoy writing!
