Speak clearly and distinctly, never mumbling your words, and while avoiding a shouting tone, speak loudly enough to ensure your remarks being heard. A very low tone of voice will be heard if the words are clearly articulated and spoken slowly enough for perfect distinctness, and is much more agreeable than hurried, garbled speech loudly uttered.
Do not sit too close to your companion in conversation, and avoid any appearance of wishing secrecy.
Loud laughing and giggling are in excessively bad taste. Do not interrupt yourself by laughing at what you are about to say.
Eschew scandal, for "in scandal as in robbery, the receiver is always thought as bad as the thief." Mimicry is the lowest and most ill-bred of all buffoonery.
Swearing, sneering, private affairs either of yourself or any other, have long ago been banished out of the conversation of well-mannered people.
Never suppose, or never appear to suppose yourself the subject of the conversation or laugh of the company.
Bashfulness is an inconvenient quality, which a great authority has stated to be "the distinguishing character of a booby." Nicknames are abominable, and are never allowed in good society. Call people and things by their right names, and avoid affectations of all kinds.
If your friends become the subject of conversation, never compare one with another, or mention the vices of one to add to the lustre of virtue of the other. Find something pleasant to say of each, that you may not earn the reputation of a backbiter.
In conversing with a foreigner, betray no impatience if he hesitates for a word to express himself, nor any ridicule if his language is faulty. If you speak his own tongue, say so when you begin the conversation, as this is never a mere display of an accomplishment, but a true kindness to "a stranger in a strange land." You are almost certain to give pleasure by so doing.
To speak constantly of public characters or distinguished people as your intimate friends, even if they are so, is a certain mark of low-breeding. Boasting of your own position, wealth, luxuries or possessions of any kind is in equally bad taste.
