I personally believe that To Kill A Mockingbird was about prejudice. Throughout the story there are several events where prejudice and judgment come into play. The story is about judging people by the things that you don't know for fact could be true. One of the main parts int he story is about Boo Radley. Supposedly since he never leaves his house and no one sees him, there are stories that he eats animals, is six-feet tall, and peeps in peoples windows at night. Everyone in Maycomb believes these stories and they start getting scared of Boo because of the stories that they themselves created. Since Boo never leaves the house and no one knows anything about them people start to make up stories to fill in what isn't there. In the end its clear that "Arthur" is nothing like Boo. Boo isn't even real he's just what people made themselves believe because they chose to believe it. Maybe the reason why he never leaves the house is simply because he doesn't want to. Arthur had been judged for several years only because people decided to judge  him and decide that he was a horrible person before they even met him. Maybe if we all just took the time to get to know people before judging them, we wouldn't have to make up stories just for our own satisfaction. And just maybe some of those people could become our friends and not be so afraid to show their face in public and contribute what they have to offer to the world.
