“A lot of Tiffany’s understanding of the world is based on Pratchett’s own experiences. Pratchett said, “It sounds amateurish to say that characters invent themselves, and in truth they don’t. That’s just a short-hand phrase. Of course the author invents them. But while the creative channel is being held open, all sorts of memories and thoughts creep out, somewhat to the owner’s surprise.” — Terry Pratchett
