“If you want to create a game like Quidditch, what you have to do is have an enormous argument with your then-boyfriend,” Rowling said in 2003. “You walk out of the house, you sit down in a pub, and you invent Quidditch. And I don’t really know what the connection is between the row and Quidditch except that Quidditch is quite a violent game and maybe in my deepest, darkest soul I would quite like to see him hit by a bludger.”
