When speaking aloud, you punctuate constantly—with body language. Your listener hears commas, dashes, question marks, exclamation points, quotation marks as you shout, whisper, pause, wave your arms, roll your eyes, wrinkle your brow. In writing, punctuation plays the role of body language. It helps readers hear you the way you want to be heard. Careful use of those little marks emphasizes the sound of your distinctive voice and keeps the reader from becoming bored or confused. . . . [Punctuation] exists to serve you. Don’t be bullied into serving it.
