Separate envelopes should be addressed to each son.
MEN. If an invitation is sent to a man, he should answer it himself; but if sent to a man and wife, the latter may answer for both.
TO CALL WITH CHAPERONE'S PERMISSION. If permission is asked, and if agreeable, a chaperone should invite a man to call upon her and her protege.
Every effort should be made to call at the specified time.
TO CALL ON WOMEN. If a woman invites a man to call without specifying the time, it is equivalent to no invitation at all.
TO CALL ON WOMEN THROUGH LETTERS OF INTRODUCTION. If a man having a letter of introduction sends the same by mail to a woman, it should be acknowledged by a written invitation to call. If the person receiving the letter does not care to receive the party, a card is sent which ends the matter.
R. S. V. P. The use of these letters—standing for "Repondez, s'il vous plait" (Answer, if you please)—is decreasing. All invitations bearing these letters should be answered at once.
These may be used on invitations to ceremonious receptions, breakfasts, luncheons, dinners, and to meet a prominent person.
WIFE. When a husband and wife are invited to
a dinner, and the former does not accept,
the wife should also decline and give her
reasons. The hostess can then invite the
wife only, who may accept.
WOMEN. A young woman receiving an invitation
to a man's supper, tea, or dinner, may
accept, if she has the consent of her mother
or chaperone, and is assured that a chaperone
will be present.
