In spite of the predominance of the engraved invitation for the most formal affairs, still small dinners, and even receptions and dancing parties, are sometimes announced by the handwritten invitations. The form should be the same as the engraved one, although to very intimate friends it should be changed to a friendly note.
Acceptances are in the form of the invitation. If that is an informal note, the acceptance or regret is sent in the same style. If the invitation is formal, the reply also should be written in the third person and be about as follows:
Mr. and Mrs. Allston B. Sinclair
accept with pleasure the kind invitation of
Mr. and Mrs. Arthur Emanuel Farrington
for dinner
on Thursday, the ninth of December
at half after eight o'clock
The reply to an invitation should be sent to the person or persons who issued it, never to any other member of the family, although such a one may be better known.
To write the word "Regrets" on one's visiting card and send it in declination of any invitation is bad form, even if the invitation come in similar shape. One should always write a note of regret.
Bachelors and widowers, who entertain at their apartments or studio or club, and army and navy officers never use the words "At Home," but always "request the pleasure (or honour) of your presence."
If one is entertaining a guest and an invitation is received, one may with propriety ask the hostess for an invitation for one's guest, if the form of entertainment is so general as to make this right and reasonable; otherwise one must decline the invitation. It would not be right to ask for another dinner invitation, or one to a select group of people, where the guest would be an intruder.
It is preferable and a much later form to use the words "Please reply," or "An early reply is requested," rather than the abbreviation "R. s. v. p." for "Rèpondez, s'il vous plaît," meaning "Reply, if you please."
If a son should return from college or other absence, and the parents wish to entertain for him, their invitations would have at the bottom the word "For" followed by his name.
