A hyperbole is an exaggerated statement or called stretching the truth.
In the short story by Truman Capote, Buddy and his cousin Miss Sooks collect money and ingredients for making fruitcake. They gather pecans and shell them, buy illegal whiskey, and make and bake the fruit cakes together. One of Buddy’s favorite things to do is to help Miss Sooks deliver the fruitcakes. Buddy is the narrator of the story and he tells who will get Miss Sooks cakes. However, he exaggerates a great deal. The following is the hyperbole in the story "A Christmas Memory."
Friends. Not necessarily neighbor friends: indeed, the larger share is intended for persons we've met maybe once, perhaps not at all. People who've struck our fancy. Like President Roosevelt. Like the Reverend and Mrs. J. C. Lucey, Baptist missionaries to Borneo who lectured here last winter. Or the little knife grinder who comes through town twice a year. Or Abner Packer, the driver of the six o'clock bus from Mobile, who exchanges waves with us every day as he passes in a dust-cloud whoosh.
