RULE 1 - Every action done in company ought to be done with some sign of respect to those that are present.
RULE 2 - When in company, put not your hands to any part of the body not usually discovered.
RULE 3 - Show nothing to your friend that may affright him.
RULE 4 - In the presence of others, sing not to yourself with a humming noise, nor drum with your fingers or feet.
RULE 5 - If you cough, sneeze, sigh, or yawn, do it not loud but privately; and speak not in your yawning, but put your handkerchief or hand before your face and turn aside.
These rules originated from the honorable Mr. Washington when he was 14 years old. I picked up a book called "By George!" written by Steven M. Selzer, published by Andrews McMeel Publishing, Kansas City. (C) 2000.
