The Ladies' Book of Etiquette, and Manual of Politeness

Neither is the lengthy, prosy, didactic reply, consistent with the submission and simplicity of youth; egotism, and egotism once removed, that is, the bringing into the topic one's own family and relations, are also antidotes to the true spirit of conversation. In general, it is wiser, more in good taste, safer, more becoming, certainly more in accordance with good breeding, to avoid talking of persons. There are many snares in such topics; not merely the danger of calumniating, but that of engendering a slippery conscience in matters of fact. A young girl, shy and inexpert, states a circumstance; she feels her deficiency as a narrator, for the power of telling a story, is a power to be acquired only by practice. She is sometimes tempted to heighten a little the incidents, in order to get on a little better, and to make more impression. She must of course defend her positions, and then she perils the sanctity of truth. Besides, few things narrow the intellect more than dwelling on the peculiarities, natural or incidental, of that small coterie of persons who constitute our world. It is, in general, a wise rule, and one which will tend much to insure your comfort through life, to avoid disclosures to others of family affairs. I do not mean to recommend reserve, or art; to friends and relations, too great frankness can hardly be practised; but, with acquaintance, the less our own circumstances are discussed, the happier, and the more dignified will our commerce with them continue. On the same principle, let the concerns of others be touched upon with delicacy, or, if possible, passed over in silence; more especially those details which relate to strictly personal or family affairs. Public deeds are, of course, public property. But personal affairs are private; and there is a want of true good breeding, a want of consideration and deference, in speaking freely of them, even if your friend is unconscious of the liberty taken.
