(I am helping a little boy find a children’s book on Native American history for a book report.)

Me: “I think this one will come in handy. It’s all about the different Native American tribes and traditions. It even includes a large map showing where the Native American tribes lived.”

Little Boy: “Thank you!”

(He walks away with his book and an adult customer approaches me.)

Customer: “Why did you do that?”

Me: “Do what?”

Customer: “Tell him those are real.”

Me: “Native Americans?”

Customer: “Yes!”

Me: “Because they are real.”

Customer: “No! They only exist in movies with cowboys!”

Me: “I can assure you that Native Americans exist.”

Customer: *mocking* “I suppose you believe cowboys really existed, too?”
