Mr. Vonnegut talked about my dad a lot and put him into a lot of his books. Sometimes he was Dad, and sometimes he was just a character Mr. Vonnegut made up. So what I would say to any of you who are wondering is this: My dad was what people called a real character, which always made us laugh because it was so literally true owing to his association with a famous fiction writer. He could also get pretty obnoxious. But he was a good man. And he definitely wasn’t crazy. At least not until the brain tumor.
