With three or more people there is something bold in the air: direct things get said which would frighten two people alone and conscious of each inch of their nearness to one another. To be three is to be in public - you feel safe.
Elizabeth BowenEach 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.
