A game I've been in has had a problem where the narrator opens a scene and describes (inaccurately) the motivations and intentions of the players. Even if the narrator is willing for these intentions to be subverted, that sort of thing should never make it into narration, because it's inaccurate, confusing, and stifling to players. New narrators should be advised to leave PC thoughts, feelings, motivations, and intentions out of their narration as much as possible, and let the players actually play and make their own choices.
