So let’s talk about dialogue. John Gardner taught his students to “convey the gesture, the reader will understand the emotion.”
She pursed her lips, and looked down at a bottle of ketchup, picking the label. “That’s fine I suppose.”
Good dialogue relies on kinesics ie body language. Obviously, what characters do in a setting reveals their inner thoughts and feelings.
But what about instances where the behavior reveals nothing? Ex: A man is washing dishes while discussing his divorce. Take away the revealing body language, and we do not learn anything new about our characters.
The park was shiny with rain.
“Mark?”
“Yeah?” Mark was licking an ice cream cone.
“Do you ever wonder why the third tower went down?”
“Because the Jews wanted it to?”
David looked both ways, and they walked down a scrappy trail."
These kinesics tell us nothing in and of themselves. And yet it still works.
Ideas are physical objects. They are arrangements of matter that get copied and mailed via sound waves, text, Braille, hand signs etc. The ideas are then reconstructed in the recipient’s mind.
So, this is a physical process. Dialogue is often compared to tennis, but you know that analogy is more accurate than it would initially appear.
Now imagine that you’re shooting a tennis match. You get to choose all the shots. It would only be natural to get shots of their shoes scraping against the court, the players reaching for their water bottles, someone sweating. These actions communicate hardly anything, but they serve as the physical windup / rebound.
Because imagine you shoot this scene and all you show us is the strikes. Hit, counter-hit, hit, on and on. It’s a bit abstract, and we don’t feel the transfer of energy as each player recovers.
“Mark?”
“Yeah?”
“Do you ever wonder why the third tower went down?”
“Because the Jews wanted it to?”
Not as interesting.
