I believe it is a quote from one of his books (the light fantastic i believe) read it earlier this year. I was hoping that I would have read more of his disc world series by now but I'm only half way through Guards! Guards!
I'm enjoying them alot and find that where I usually devour books, I like to savour these and only read a little bit every day with my hubby.
Maybe by next year I would have read the entire disc world series and would have moved on to the long earth.
