It is high time we start learning how to engage in conversations. Especially, men.

The most important requisite for a good conversational power is education, and, by this is meant, not merely the matter you may store in your memory from observation or books, though this is of vast importance, but it also includes the developing of the mental powers, and, above all, the comprehension.

An English writer says, “A man should be able, in order to enter into conversation, to catch rapidly the meaning of anything that is advanced; for instance, though you know nothing of science, you should not be obliged to stare and be silent, when a man who does understand it is explaining a new discovery or a new theory; though you have not read a word of Blackstone, your comprehensive powers should be sufficiently acute to enable you to take in the statement that may be made of a recent cause; though you may not have read some particular book, you should be capable of appreciating the criticism which you hear of it.

Without such power—simple enough, and easily attained by attention and practice, yet too seldom met with in general society—a conversation which departs from the most ordinary topics cannot be maintained without the risk of lapsing into a lecture; with such power, society becomes instructive as well as amusing, and you have no remorse at an evening’s end at having wasted three or four hours in profitless banter, or simpering platitudes.

This facility of comprehension often startles us in some women, whose education we know to have been poor, and whose reading is limited. If they did not rapidly receive your ideas, they could not, therefore, be fit companions for intellectual men, and it is, perhaps, their consciousness of a deficiency which leads them to pay the more attention to what you say.
It is this which makes married women so much more agreeable to men of thought than young ladies, as a rule, can be, for they are accustomed to the society of a husband, and the effort to be a companion to his mind has engrafted the habit of attention and ready reply.”... stay with me

Never interrupt any one who is speaking; it is quite as rude to officiously supply a name or date about which another hesitates, unless you are asked to do so. Another gross breach of etiquette, is to anticipate the point of a story which another person is reciting, or to take it from his lips to finish it in your own language.
Some persons plead as an excuse for this breach of etiquette, that the reciter was spoiling a good story by a bad manner, but this does not mend the matter. It is surely rude to give a man to understand that you do not consider him capable of finishing an anecdote that he has commenced.

It is ill-bred to put on an air of weariness during a long speech from another person, and quite as rude to look at a watch, read a letter, flirt the leaves of a book, or in any other action show that you are tired of the speaker or his subject.

In a general conversation, never speak when another person is speaking, and never try by raising your own voice to drown that of another. Never assume an air of haughtiness, or speak in a dictatorial manner; let your conversation be always amiable and frank, free from every affectation.

Put yourself on the same level as the person to whom you speak, and under penalty of being considered a pedantic idiot, refraining from explaining any expression or word that you may use.
