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 the way you want to be heard.
