Life is serious all the time, but living cannot be. You may have all the solemnity you wish in your neckties, but in anything important (such as sex, death, and religion), you must have mirth or you will have madness.
The sex relation is not a personal relation. It can be irresistibly desired and rapturously consummated between persons who could not endure one another for a day in any other relation.
I try to tell the best story, and the story that has some heart and some genuine terror and some social commentary and some comedy and some romance and some sex and some violence.
