“The DYNNE paused in the doorway with a look of extreme horror on his almost featureless face, and the doctor shuddered in a way that sounded very much like a fast-moving freight train being derailed into a mountain of custard.”

–Norton Juster, The Phantom Tollbooth

How do your characters express fear? What are their greatest fears? How do they react to other people who are afraid? Come up with a scenario that involves at least two characters. One of the characters should be very frightened by your scenario and the other one is not affected. Describe what your characters think, feel, and do. How do they react to one another? How do they deal with the situation?
