I felt after I finished Slaughterhouse-Five that I didn't have to write at all anymore if I didn't want to. It was the end of some sort of career. I don't know why, exactly. I suppose that flowers, when they're through blooming, have some sort of awareness of some purpose having been served. Flowers didn't ask to be flowers and I didn't ask to be me. At the end of Slaughterhouse-Five...I had a shutting-off feeling...that I had done what I was supposed to do and everything was OK .
