A call should not be less than fifteen minutes in duration, nor should it be so long as to become tedious. A bore is a person who does not know when you have had enough of his or her company, and gives more of it than is desirable. Choose a time to leave when there is a lull in the conversation, and the hostess is not occupied with fresh arrivals. Then take leave of your hostess, bowing to those you know as you leave the room, not to each in turn, but let one bow include all. Calls ought to be made within three days after a dinner or tea party, if it is a first invitation; and if not, within a week. After a party or a ball, whether you have accepted the invitation or not, you call within a week. A lady who has no regular reception day will endeavor to receive callers at any time. If she is occupied, she will instruct her servant to say that she is engaged; but a visitor once admitted into the house must be seen at any inconvenience. A lady should never keep a caller waiting without sending to see whether a delay of a few minutes will inconvenience the caller. Servants should be instructed to return and announce to the person waiting that the lady will be down immediately. Any delay whatever should be apologized for. If, on making a call, you are introduced into a room where you are unknown to those assembled, at once give your name and mention upon whom your call is made. In meeting a lady or gentleman whose name you cannot recall, frankly say so, if you find it necessary. Sensible persons will prefer to recall themselves to your memory rather than to feel that you are talking to them without fully recognizing them. To affect not to remember a person is despicable, and reflects only on the pretender. Gentlemen, as well as ladies, when making formal calls, send in but one card, no matter how many members of the family they may wish to see. If a guest is stopping at the house, the same rule is observed. If not at home, one card is left for the lady, and one for the guest. The card for the lady may be folded so as to include the family.
