Never notice it if others make mistakes in language. To notice by word or look such errors in those around you, is excessively ill-bred.
Avoid raillery and sarcasm in social parties. They are weapons which few can use; and because you happen to have a razor in your possession, that is no reason why you should be allowed to cut the throats of the rest who are unarmed. Malicious jests at the expense of those who are present or absent, show that he who uses them is devoid both of the instincts and habits of a gentleman. Where two individuals or the whole company agree to banter each other with good-natured sallies of wit, it is very pleasant, but the least taint of ill-nature spoils all.
If upon the entrance of a visitor you continue a conversation begun before, you should always explain the subject to the new-comer.
If there is any one in the company whom you do not know, be careful how you let off any epigrams or pleasant little sarcasms. You might be very witty upon halters to a man whose father had been hanged. The first requisite for successful conversation is to know your company well.
Carefully avoid subjects which may be construed into personalities, and keep a strict reserve upon family matters. Avoid, if you can, seeing the skeleton in your friend's closet, but if it is paraded for your special benefit, regard it as a sacred confidence, and never betray your knowledge to a third party.
Listen attentively and patiently to what is said. It is a great and difficult talent to be a good listener, but it is one which the well-bred man has to acquire, at whatever pains. Do not anticipate the point of a story which another person is reciting, or take it from his lips to finish it in your own language. To do this is a great breach of etiquette.
Dr. Johnson, whose reputation as a talker was hardly less than that which he acquired as a writer, prided himself on the appositeness of his quotations, the choice of his words, and the correctness of his expressions. Had he lived in this "age of progress," he would have discovered that his lexicon was not only incomplete, but required numerous emendations. We can fancy the irritable moralist endeavoring to comprehend the idea which a young lady wishes to convey when she expresses the opinion that a bonnet is "awful," or that of a young gentleman, when he asserts that his coat is "played out!"
Avoid the use of proverbs in conversation, and all sorts of cant phrases. This error is, I believe, censured by Lord Chesterfield, and is one of the most offensively vulgar which a person can commit.
It is bad manners to satirize lawyers in the presence of lawyers, or doctors in the presence of one of that calling, and so of all the professions. Nor should you rail against bribery and corruption in the presence of politicians, (especially of a New York politician,) or members of Congress, as they will have good reason to suppose that you are hinting at them. It is the aim of politeness to leave the arena of social intercourse untainted with any severity of language, or bitterness of feeling. There are places and occasions where wrong must be exposed and reproved, but it is an unpardonable piece of rudeness to attempt such things at your own or another's social party, where everything is carefully to be avoided that can in the least disturb the happiness of any one. For this reason all kinds of controversies are, as a general rule, to be avoided at such times.
Any conversation (that is not interdicted by decency and propriety) which can be pleasing to the whole company, is desirable. Amusement, more than instruction even, is to be sought for in social parties. People are not supposed to come together on such occasions because they are ignorant and need teaching, but to seek amusement and relaxation from professional and daily cares. All the English books on etiquette tell you that "punning is scrupulously to be avoided as a species of ale-house wit," and a savage remark of Dr. Johnson is usually quoted on the subject. But punning is no more to be avoided than any other kind of wit; and if all wit is to be banished from the social circle, it will be left a stupid affair indeed. All kinds of wit, puns by no means excepted, give a delightful relish to social parties when they spring up naturally and spontaneously out of the themes of conversation. But for a man to be constantly straining himself to make jokes is to make himself ridiculous, and to annoy the whole company, and is, therefore, what no gentleman will be guilty of.
Talk as little of yourself as possible, or of any science or business in which you have acquired fame. There is a banker in New York who is always certain to occupy the time of every party he gets into, by talking of his per cents, and boasting that he began life without a cent--which every one readily believes; and if he were to add that he began life in a pig-pen, they would believe that too.
If you put on a proud carriage, people will want to know what there is in you to be proud of. And it is ten to one whether they value your accomplishments at the same rate as you. And the higher you aspire, they will be the more desirous to mortify you.
Nothing is more nauseous than apparent self-sufficiency. For it shows the company two things, which are extremely disagreeable: that you have a high opinion of yourself, and that you have comparatively a mean opinion of them.
It is the concussion of passions that produces a storm. Let an angry man alone, and he will cool off himself.
It is but seldom that very remarkable occurrences fall out in life. The evenness of your temper will be in most danger of being troubled by trifles which take you by surprise.
It is as obliging in company, especially of superiors, to listen attentively, as to talk entertainingly.
Don't think of knocking out another person's brains, because he differs in opinion from you. It will be as rational to knock yourself on the head, because you differ from yourself ten years ago.
If you want to gain any man's good opinion, take particular care how you behave, the first time you are in company with him. The light you appear in at first, to one who is neither inclined to think well or ill of you, will strongly prejudice him either for or against you.
Good humor is the only shield to keep off the darts of the satirical railer. If you have a quiver well stored, and are sure of hitting him between the joints of the harness, do not spare him. But you had better not bend your bow than miss your aim.
The modest man is seldom the object of envy.
In the company of ladies, do not labor to establish learned points by long-winded arguments. They do not care to take too much pains to find out truth.
You will forbear to interrupt a person who is telling a story, even though he is making historical mistakes in dates and facts. If he makes mistakes it is his own fault, and it is not your business to mortify him by attempting to correct his blunders in presence of those with whom he is ambitious to stand well.
In a dispute, if you cannot reconcile the parties, withdraw from them. You will surely make one enemy, perhaps two, by taking either side in an argument when the speakers have lost their temper.
Do not dispute in a party of ladies and gentlemen. If a gentleman advances an opinion which is different from ideas you are known to entertain, either appear not to have heard it, or differ with him as gently as possible. You will not say, "Sir, you are mistaken!" "Sir, you are wrong!" or that you "happen to know better;" but you will rather use some such phrase as, "Pardon me--if I am not mistaken," etc. This will give him a chance to say some such civil thing as that he regrets to disagree with you; and if he has not the good manners to do it, you have, at any rate, established your own manners as those of a gentleman in the eyes of the company. And when you have done that, you need not trouble yourself about any opinions he may advance contrary to your own.
If you talk sentences, do not at the same time give yourself a magisterial air in doing it. An easy conversation is the only agreeable one, especially in mixed company.
Be sure of the fact, before you lose time in searching for a cause.
If you have a friend that will reprove your faults and foibles, consider you enjoy a blessing, which the king upon the throne cannot have.
In disputes upon moral or scientific points, ever let your aim be to come at truth, not to conquer your opponent. So you never shall be at a loss in losing the argument, and gaining a new discovery.
