Malamud also experiments with tense, the way in which a writer uses verbs to denote time or duration. Authors write in past tense when they want to communicate how something "happened," in present tense when they want to show how something "is happening," or future tense, when they want to say how something "will happen." The tense of a story helps to determine how the reader reacts to the tale. Most fiction is told in past tense, where the narrator recounts something that has happened. Present tense is more rare because it tells of something that is happening right now, and most readers find it easier to believe a tale if it is something that has already happened.
