Hyperbole, or overstatement, is a common device used in literature to emphasize or illustrate the writer's points or metaphors. The 'dramatic' element in hyperbole allows the story to explore the issues of the situations involved, and characters representing points of view to be more easily contrasted. In hyperbolic expression, anything can be overstated to the point of absurdity, to give a high impact to the narrative and further developments of the concepts.
