Every story has a main character that is different from the rest of the characters in the story. The types of characters are static characters which stay the same in the story, or a developing character. In the story "I"m a Fool" by Sherwood Anderson, the main character is clearly a developing character that develops throughout the story and is not a static character.
The main character is developing because in the story he talks about how what he did was totally foolish and that he is learning from his mistakes. He is also a round character in that he is complex and there are many details about him. He has the three-dimensional quality of a real person because in this story, he is dramatized because he acts the way he is described. The tone of the story and the diction used also shows the complexity of the character. The way the author used bad grammer shows how three-dimensional and how realistic the character truly is.
The author presents this character in indirect presentation. The author makes the character the narrator of the story and makes him explain in his own dialect and through his actions what he is like. For example he says "To tell you the truth, I felt a little foolish that I should be sitting in the grandstand at all." He explains through his own words what he feels like. Also it is written "She wasn't stuck on me because of the lie about my father being rich and all that." It's saying that because of his actions, she wasn't stuck on him.
Characters in a story can be presented in different ways and they can be either static or developing. The main character is usually a developing character that is presented realistically in the story so you can truly feel what it would be like to be him.
