Did you know that the U.S. postal service handles 40% of the world's mail volume? Japan is the second largest carrier of cards and letters, but it handles only 8% of the world's mail. Perhaps the reason that the U.S. handles such a large volume of mail is the large number of personal letters American citizens write. Personal letters do not require a strict format, but they do have a few guidelines. The date should be written at the top of the letter, either in the center or in the right-hand corner. The salutation, "Dear ____,"should begin the letter and should be followed by a comma instead of a colon which is used in the salutation of a business letter. The body of the letter should sound like you, and say the things you intend to say. Unlike in a business letter, you can use slang words, dashes, smiley faces, sentence fragments, and other kinds of casual forms of communication. Closing for personal letters are also a matter of personal preference. While a business letter requires you to use more formal closings such as "Sincerely,""Regards," or "Best Wishes," a personal letter can end with more casual phrases such as "Later," "Talk to you Soon," Or "Bye." As with the rest of the letter, the closing should express your own feelings.
