A newly married couple send out cards immediately after the - ceremony, to their friends and acquaintance, who, on their part, return either notes or cards of congratulation on the event. As soon as the lady is settled in her new home, she may expect the calls of her acquaintance; for which it is not absolutely necessary to remain at home, although politeness requires that they should be returned as soon as possible. But, having performed this, any further intercourse may be avoided (where it is deemed necessary) by a polite refusal of invitations. Where card are to be left, the number must be determined according to the various members of which the family called upon is composed. For instance, where there are the mother, aunt, and daughters (the latter having been introduced to society), three cards should be left. See 2865.
