George Washington penned 54 “Rules of Civility” that can be found here. When I first found these, I immediately loved them based upon reading only the first two:
1. Every action in company ought to be with some sign of respect to those present.
2. (and my favorite) In the presence of others sing not to yourself with a humming voice, nor drum with your fingers or feet.
The number of times that I have sat through conference meetings with a 250-pound 6′ 4″ grown man, bouncing his leg and shaking half of the room! George Washington would not have approved !
This list of rules is an excerpt from the excellent publication Book of Virtues.
