What is the theme in The Nick Adams Stories by Ernest Hemingway?

Fear is another theme in the story. Nick's timidity is a theme which is explored throughout the stories, but especially in the first three sections. In "Three Shots" Nick is so frightened by the thought of death that he fires the rifle into the air to summon his father and uncle back and then lies about there being a wild animal. In "Indian Camp" he is forced to face his fear of death when he accidentally sees an Indian man who has slit his own throat.
