Each line of dialogue should add to the story, usually by adding to a character. Dialogue advancing the plot but not contributing to the story results from including dialogue for the sake of dialogue or overzealous editing. Inexperienced writers should avoid using dialogue merely because they have been told dialogue is essential. Indirect Dramatic Effect Remember that all fiction, and some non-fiction, requires drama to retain readers. Do not confuse dramatic effect with melodrama.
Dramatic dialogue resembles a poker game or negotiation.
In dramatic dialogue the speakers avoid being direct. Questions and statements are subtle, as they often are in reality. People learn to be indirect as children. Those who do not learn are considered tactless. Well-written dialogue mirrors this reality.
