One of the biggest sayings in magic is that a true magician never reveals their secrets. This has become taken at face value in our culture. Some people accept it for what it is, while others become frustrated. No matter your feelings on the matter, many accept it as an inevitability.
Many people do not bother to ask “why” this code exists. No, it is not to make the magician feel smarter or to hide some dark conspiracy from our patrons. Magicians simply recognize that keeping tricks a secret is the very reason why our trade is so entertaining.
