Conflict is “the struggle that grows out of the interplay of two opposing forces. Conflict provides interest, suspense, and tension. At least one of the opposing forces is customarily a person. This person, usually the protagonist, may be involved in conflicts of four different kinds:
(1) a struggle against nature
(2) a struggle against another person, usually the antagonist
(3) a struggle against society
(4) a struggle for mastery by two elements within the person”
