a friend or acquaintance, especially if she is desirous of extending an invitation. Instead of leaving the card, she may even, for lack of time and opportunity, post it with an engraved or written invitation.
A man or woman unable to accept an invitation, extended by a hostess to whom he or she is a stranger, is obligated to leave cards within two weeks after the entertainment. Similarly, the guests, men and women, invited to the ceremony of a church wedding, leave cards for the bride's mother within two weeks after the wedding. Even though one is a stranger to the mother, this card must be left as a matter of courtesy and social obligation. People who receive cards announcing a marriage are also expected to leave cards for the mother of the bride. A friend of the groom who is a stranger to the bride and her family, and who finds that he is unable to attend the ceremony to which he has been invited, need not pay a call, but must leave a card for the bride's mother a week or two after the wedding.
Other occasions requiring card-leaving are those inquiries regarding the health and condition of a friend; sympathy and good feeling in the event of some misfortune; condolence; congratulation; and upon announcing a prolonged absence from, or a reëntrance into, society. A change of address is also usually made known by means of card-leaving.
If one is invited to an afternoon or evening reception, and finds it impossible to attend, cards should be sent either by mail or messenger, so that they reach the hostess on the day of her entertainment.
