Each piece of dialogue MUST be "something happening". . .The "amusing" for its OWN sake should above all be censored. . .The functional use of dialogue for the plot must be the first thing in the writer's mind. Where functional usefulness cannot be established, dialogue must be left out.

During dialogue, the characters confront one another. The confrontation is in itself an occasion. Each one of these occasions, throughout the novel, is unique.
