"I know there are a lot of readers that think I've got a very crappy marriage just because of the things going on with Rick and Lori but there's really nothing that's been like a mirror. I'm just making this stuff up"

Robert Kirkman is referring to his popular comic book series, The Walking Dead. In the series, Rick and Lori have a tumultuous relationship, which has actually led some readers to believe that Kirkman's own marriage is in a similar state. However, Kirkman is quick to explain that this is not the case. He is merely utilizing his creativity to develop the story and the characters, and the events that happen in the comic are not reflective of his own life. He is merely using his imagination to craft a compelling narrative. Kirkman's quote is a pointer that fiction is just that - fiction. It is not a reflection of truth, and readers ought to not make assumptions about the author's life based upon the stories they check out.
