The “other one”

The other day a boy about 10 years old came up to the reference desk.

Boy: “I’m looking for a biography on Neil Armstrong and his comeback from cancer.”
Me: [Know right away this kid wasn't talking about Neil Armstrong.] “Neil Armstrong? The astronaut?”
Boy: “No, no. The other one.”
Me: [Mental eye-roll] “Do you mean Lance Armstrong? The cyclist?”
Boy: “Yeah, him!”

As it happened, we had several books on Lance Armstrong and the kid went home happy. I wonder if that kid even knows who Neil Armstrong is.
