A last-moment vacancy:
A last-moment vacancy may occur in a dinner party. To send an invitation to fill such a vacancy is a matter requiring tact, and the recipient should be made to feel that you are asking him to fill in as a special courtesy. Frankly explain the situation in a short note. It might be something like this:
500 Park Avenue,
February 16, 1922.
My dear Mr. Jarrett,
Will you help me out? I am giving a little dinner party to-morrow evening and one of my guests, Harry Talbot, has just told me that on account of a sudden death he cannot be present. It is an awkward situation. If you can possibly come, I shall be very grateful.
Cordially yours,
Katherine G. Evans.
Mr. Harold Jarrett
628 Washington Square South
