If someone asks you where you get your characters... and they're sure to do that... you always say, "He's a combination of a lot of people I have known." That way, if your character is a damn fool, nobody will want to identify with him... To tell the truth, I don't know how a man gets a character for a story, anymore than I know how he falls in love. I don't know if his characters spring full-blown from his head, or if he sees a man walking down the street and recognises him instantly... I doubt any writer knows for sure where his characters come from.
