In Fahrenheit 451, Ray Bradbury uses many different types of literary devises to add to his characters. "The thought had been with him many times recently but now he remembered how it was that day in the city park when he had seen that old man in the black suit hide something, quickly, in his coat." This is an example of imagery and of a memory Montag has of Faber. This keeps the audiance in touch with Montag and gives a more personal feel.
