When an individual writes a letter to his or her father, he or she should include a salutation that addresses the father, such as "Dear Dad," followed by the body that contains the letter's content and a closing like "Love" that ends the letter. The body of the letter should be divided into paragraphs to make the letter easy to read.
When formatting a letter, the heading includes pertinent information about the purpose of the letter. For personal letters, the heading includes the date. The opening states the opening salutation, which is directed to the recipient of the letter. All the information that needs to be communicated is found in the body. The closing includes the writer's signature.
