One may never ask for an invitation for oneself anywhere! And one may not ask for an invitation to a luncheon or a dinner for a stranger. But an invitation for any general entertainment may be asked for a stranger—especially for a house-guest.
Dear Mrs. Worldly,
A young cousin of mine, David Blakely from Chicago, is staying with us.
May Pauline take him to your dance on Friday? If it will be inconvenient for you to include him, please do not hesitate to say so frankly.
Very sincerely yours,
Caroline Robinson Town.
Dear Mrs. Town,
I shall be delighted to have Pauline bring Mr. Blakely on the tenth.
A man might write for an invitation for a friend. But a very young girl should not ask for an invitation for a man—or anyone—since it is more fitting that her mother ask for her. An older girl might say to Mrs. Worldly, "My cousin is staying with us, may I bring him to your dance?" Or if she knows Mrs. Worldly very well she might send a message by telephone: "Miss Town would like to know whether she may bring her cousin, Mr. Michigan, to Mrs. Worldly's dance."There may be times when you receive an invitation to an occasion or have already received one and find that you now have a house-guest on the day of the event. It may also happen that there is a friend or acquaintance that you would like to bring to an event where the invitation did not expressly state that guests could bring a date. These are not usual situations and most hosts are prepared for them, if they receive your request in advance. Never just show up with someone in tow especially if it is to a lunch or dinner, simply because the host may not have prepared enough extra food for several guests to show up with unexpected strangers. It is just fine to ask for an invitation to a party or other more general occasion.
