I never deliberately sat down and ‘created’ a character in my life. I begin to write incidents out of real life. One of the persons I write about begins to talk this way and one another, and pretty soon I find that these creatures of the imagination have developed into characters, and have for me a distinct personality. These are not ‘made,’ they just grow naturally out of the subject. That was the way Tom Sawyer, Huck Finn and other characters came to exist. I couldn’t to save my life deliberately sit down and plan out a character according to diagram. In fact, every book I ever wrote just wrote itself. I am really too lazy to sit down and plan and fret to ‘create’ a ‘character.’ If anybody wants any character ‘creating,’ he will have to go somewhere else for it. I’m not in the market for that. It’s too much like industry.
