Good manners, to those one does not love, are no more a breach of truth, than "your humble servant," at the bottom of a challengeis; they are universally agreed upon, and understand to be things of course. They are necessary guards of the decency and peace of society.
Lord ChesterfieldCautiously avoid speaking of the domestic affairs either of yourself, or of other people. Yours are nothing to them but tedious gossip; and theirs are nothing to you.
Lord Chesterfield
