Invitations to children are addressed, Miss Katherine Smith and Master Robert Smith.
Do not write "The Messrs. Brown" in addressing a father and son. "The Messrs. Brown" is correct only for unmarried brothers.
Although one occasionally sees an envelope addressed to "Mr. and Mrs. Jones," and "Miss Jones" written underneath the names of her parents, it is better form to send a separate invitation addressed to Miss Jones alone. A wedding invitation addressed to Mr. and Mrs. Jones and family is not in good taste. Even if the Jones children are young, the Misses Jones should receive a separate envelope, and so should Master Jones.
One Last Remark
Write the name and address on the envelope as precisely and as legibly as you can. The post-office has enough to do in deciphering the letters of the illiterate, without being asked to do unnecessary work for you!
Business Letters
Business letters written by a private individual differ very little from those sent out from a business house. A lady never says "Yours of the 6th received and contents noted," or "Yours to hand," nor does she address the firm as "Gentlemen," nor does she ever sign herself "Respectfully." A business letter should be as brief and explicit as possible. For example:
Tuxedo Park
