A well-bred man, receiving an invitation to dine with a friend should reply to it immediately, whether he accepts or declines it.
He should be punctual to the hour named in the invitation, five or ten minutes earlier if convenient, but not one instant later. He must never, unless he has previously asked permission to do so, take with him any friend not named in his invitation. His host and hostess have the privilege of inviting whom they will, and it is an impertinence to force them to extend their hospitality, as they must do if you introduce a friend at their own house.
Speak, on entering the parlor of your friend, first to the hostess, then to the host.
When dinner is announced, the host or hostess will give the signal for leaving the drawing-room, and you will probably be requested to escort one of the ladies to the table. Offer to her your left arm, and at the table wait until she is seated, indeed wait until every lady is seated, before taking your own place.
In leaving the parlor you will pass out first, and the lady will follow you, still holding your arm. At the door of the dining-room, the lady will drop your arm. Pass in, then wait on one side of the entrance till she passes you, to her place at the table.
If there are no ladies, you may go to the table with any gentleman who stands near you, or with whom you may be conversing when dinner is announced. If your companion is older than yourself, extend to him the same courtesy which you would use towards a lady.
There are a thousand little points to be observed in your conduct at table which, while they are not absolutely necessary, are yet distinctive marks of a well-bred man.
If, when at home, you practice habitually the courtesies of the table, they will sit upon you easily when abroad; but if you neglect them at home, you will use them awkwardly when in company, and you will find yourself recognized as a man who has “company manners,” only when abroad.
I have seen men who eat soup, or chewed their food, in so noisy a manner as to be heard from one end of the table to the other; fill their mouths so full of food, as to threaten suffocation or choking; use their own knife for the butter, and salt; put their fingers in the sugar bowl; and commit other faults quite as monstrous, yet seem perfectly unconscious that they were doing anything to attract attention.
Try to sit easily and gracefully, but at the same time avoid crowding those beside you.
