I once talked to a guy who claimed to be the secret son of Jim Morrison. He had a copy of a Morrison biography with him. He wore flannel shirts as jackets in Omaha in 1991 and claimed to be an advanced practitioner of Muay Thai. It was all completely absurd and not even a tiny bit plausible, any part of it. I didn’t believe any of it.
But there seemed to be no reason to challenge him. I just let him talk. It didn’t matter.
