The Need from Dialogue

"I often saw the editor I worked for wander over to the slush pile table and riffle quickly through half a dozen manuscripts before handing me one to read. I was mystified: What could she possibly see from ten seconds of flipping pages? When I asked her, she answered, 'I'm looking for lots of dialogue.' Questioned further, she explained that one of the major flaws in novels from beginning writers was too much narration, not enough lively conversation between characters. Dialogue is vital in getting a reading from an unagented script, not just well written dialogue, but plenty of it." (Confessions of a First Reader, by Roy Sorrels)
