In "An Echo in the Bone" by Diana Gabaldon, Uncle Hal expresses a unique perspective on communication. He believes that formalities such as salutations and closings are unnecessary when writing to someone, as the essential details—the recipient's address and the letter's seal—make the sender and message clear. This approach reflects his practical and direct nature.

Uncle Hal's view emphasizes efficiency in correspondence, suggesting that he does not entertain responses from those he considers foolish. His focus on clarity over traditional letter-writing etiquette showcases a straightforward attitude, reinforcing his belief that the intended recipient should easily understand the message without unnecessary formalities.
