Often the narcissist believes that other people are "faking it", leveraging emotional displays to achieve a goal. He is convinced that their ostensible "feelings" are grounded in ulterior, non-emotional motives. Faced with other people's genuine emotions, the narcissist becomes suspicious and embarrassed. He feels compelled to avoid emotion-tinged situations, or worse, experiences surges of almost uncontrollable aggression in the presence of expressed sentiments. They remind him how imperfect he is and how poorly equipped.
