The matter of paying the first call is often a very delicate one. Frequently sensitive people are offended by some unconscious slight on the part of a friend. The following rules will help those who are in doubt, and who are anxious to follow the correct usage, and thus avoid blunders that may result in broken friendships.

An unmarried woman always pays the first call of the season upon a matron. The elder of two women is entitled to the first visit. This same rule holds true among men, when the question of the formal call arises. In large cities, when the recognized winter period for exchanging formal calls opens, very little attention is paid to the matter of the first calls of the season. It is usually dependent upon convenience and inclination of individuals, and upon the settling of an at-home day. Sometimes women who are exceptionally punctilious make their first calls with reference to courtesies extended or received in the foregoing season. Thus, they refer to their calling lists of the preceding winter, in deciding on whom to make the first calls. However, this is entirely in the hands of the individual.

There are certain obligatory calls that must be made, if one wishes to be in accord with the laws of etiquette. These are sometimes referred to as "duty calls." For instance, it is essential for all wedding guests, bridesmaids, ushers, and for the best man, maid of honor and matron of honor to call on the bride's mother within three weeks after her daughter's wedding. They must also call upon the bride as soon as she returns from her honeymoon. If the wedding was held at the home of a sister or other relative, the call is made to the lady who acted in the capacity of hostess. The guests at a home wedding, wedding reception or breakfast, are also obligated to call on the bride's mother, and on the bride herself, in due course.

It is distinctly important for all guests, both men and women, at a formal dinner to call upon the hostess within two or, at the most, three weeks after the dinner. This holds true even if the invitation was not accepted. The dinner call should be paid promptly; if a man or woman who has not accepted an invitation to dinner does not call within three weeks, the hostess has every reason to believe that he, or she, does not desire her friendship and hospitality. This same holds true of balls, suppers, parties and receptions. Not to accept an invitation, and not to call, is a gross incivility and reflects upon the good manners of the person who has neglected to make the obligatory call.
