A man approached me on the street. He stopped me and said that there was a dot on my head. I went home and looked in the mirror, but I did not see a dot on my head. To my fascination another person stopped me on the street again; he carried the same message. I told him that I saw no dot on my head. The man told me that I could not see it, hear it, or taste it. This confused me, but there must have been some reason as to why all these people kept telling me there was a dot on my head. I asked him if there was some way it could manifest itself in the physical world. He told me that he had faith that there was a dot on my head. I asked him if there was any evidence at all for this dot on my head. He replied by showing me a book. The book he showed me was 2,000 year old archaic text written by tribesmen. I pointed this out to him, and he told me that this book was law. I simply walked away. It turned out there was a community of people who also did not see a dot on my head.
