Alohomora Post 17 Magician's code

Remember the magician's code: 1. Don't reveal the secret, even to your best friend! 2. Don't perform the same trick twice before the same audience, 3. Don't do any trick until you have practiced and perfected it thoroughly, 4. Don't knock other magicians. Do unto them as you would have them do unto you.
