I have never lied about my relationship with Bill Clinton. The only proven liar, at this point, and the only admitted liar, is Bill Clinton; not Gennifer Flowers, not Kathleen Willey, not Paula Jones and not Monica Lewinsky, at this point. He is the only proven liar.
Basically you come up with the fictional idea and you start writing that story, but then in order to write it and to make it seem real, you sometimes put your own memories in. Even if it's a character that's very different from you.
