Everywhere in these days one hears the same story. The American woman in her home, whether in city or country, is becoming as dependent upon the telephone as her husband in his store or office. She orders the family dinner by telephone, upbraids her dressmaker by telephone and electioneers by telephone for the presidency of her club. If she happens to live in one of the houses equipped with the latest pattern of telephone apparatus she gives her orders to the cook in the kitchen without leaving her chair in the sitting-room, for the telephone has taken the place of the speaking-tube in the up-to-date city residence. No habit grows by what it feeds on more rapidly than the telephone habit.
Things have come to such a pass that an elaborate code of telephone etiquette has come into being. A first rule has been formulated to the effect that messages shall be sent only to social equals. It is a breach of good telephone form for Mrs. A to ask her servant to call up Mrs. B; and Mrs. B, if snubbed in that way, would be quite satisfied in cutting Mrs. A’s acquaintance. Of course, it is possible for Mrs. A to send her message by means of a servant, but in order not to give offence it is necessary that Mrs. A’s servant repeat Mrs. A’s message to Mrs. B’s servant and that Mrs. B’s servant take the message to Mrs. B.
When, however, Mrs. A calls for Mrs. B it is to be expected that a servant may respond. In that case it is perfectly proper for Mrs. A to give the servant a message for Mrs. B, but care must be observed if, for instance, an invitation to drive or to dinner is being extended, that it be expressed in language as carefully chosen as any that a gentlewoman would use in a written note. In general, Mrs. B, if she is at all punctilious, will prefer to go to the telephone and to accept or decline the invitation personally. If she permits the servant to make the reply it is incumbent upon her to have the message worded with a formality equal to that used by Mrs. A.
