excerpt from How to Behave: A Pocket Manual of Republican Etiquette by Samuel R. Wells
Do not fall into the absurd error of supposing that you may do as you please at home—that is, unless you please to behave in a perfectly gentlemanly or ladylike manner. The same rights exist there as elsewhere, and the same duties grow out of them, while the natural respect and affection which should be felt by each member of the family for all the other members, add infinitely to their sacredness. Let your good manners, then, begin at home.
