Customer: “I’m looking for a book about a football player.”

Me: “Do you know the title or author?”

Customer: “It’s about a kid who plays football.”

Me: “Is it fiction or nonfiction?”

Customer: “Which is the real one?”

Me: “You mean which is a true story?”

Customer: “Yeah.”

Me: “Nonfiction books are true stories. Is it a biography or autobiography?”

Customer: *exasperated* “What’s the difference?”

Me: “Biographies are written by someone else about a person, autobiographies are written by the person themselves.”

Customer: “I doubt he wrote it; he’s a football player. Do you know how many hits those guys take to the head?!”
