Do not whisper in company; nothing can be more vulgar. Neither should two in a gathering converse together in a foreign language, not understood by the others present, or talk blindly in a manner unintelligible only to themselves. Should, however, a distinguished foreigner to whom the language is almost unknown be among the guests, it is a mark of courtesy for as many as possible to converse in his native tongue.
Do not immediately break off the conversation upon persons entering the room. It is too apt to leave the impression upon their minds that the discourse was of them. In carrying on a conversation after newcomers enter the room, briefly recapitulate what has gone before, that the thread of the story may be complete for them. Look at those with whom you are talking, but never stare.
Profanity is the last and most inexcusable sin committed against good manners and propriety. The man who will deliberately use profane language in the drawing-room, or before women and children, or aged men, should be considered without the pale of good society.
Language coarse in its tendency is open to the same criticism, and remarks and stories that carry a double meaning cannot be too severely condemned. If it is at any time possible for a woman to receive such a story in its innocent sense, let her do it, showing by some remark the light in which it is taken; otherwise, she should be apparently blind and ignorant as to its meaning.
Avoid affectations. In conversation make use of long words as little as possible, and wherever a short and easily understood one is suitable to express your meaning, choose it in preference to one of polysyllabic proportions.
Use of the Lips and Facial Expressions.
Do not cover the lips with the hand, or a fan, while speaking. To do so shows nervousness and a lack of social training. Besides this, much of the expression of the face lies in the mouth. This is shown by all actors, readers and public speakers, who, as a rule, appear before their audiences with closely-shaven faces, that no portion of the varying changes of the lips may be lost.
Never, if you are a man, speak lightly of women. Nothing so surely lowers your own standard in the eyes of all sensible people. Never hurt the feelings of others. Never allude publicly to times when you have known them in less affluent circumstances than the present.
Be very careful to guard against over much laughing. Nothing gives a sillier appearance than spasms of laughter upon the slightest provocation. It soon grows into a very disagreeable habit. Smile frequently, if need be, but be moderate in laughter. A very little reasoning will serve to do this; and the reflection that few grown people laugh well will aid still farther in curbing the propensity.
Let your greeting of acquaintances be free from boisterousness and familiarity. Do not bring your hand down heavily upon their shoulder, nor emphasize your sentences with pushes and punches of an active elbow, nor fling your arms about their necks or shoulders. To some fastidious persons these boorish acts are a positive insult. An affectation of boisterous familiarity more often betrays a feeling of social inferiority than absolute shyness or timidity does.
