Whenever anything bad happens, people blame it on Boo Radley.
Unfortunately, making fun of Boo and the Radleys is not just for children.
Miss Stephanie Crawford seems to be the source of most of the rumors about Boo Radley. In fact, Scout notes that she “had more to say about the Radleys than anybody in Maycomb” (ch 4). She accuses him of peeping in her windows, “his head was like a skull lookin' at her” (ch 1). Miss Stephanie is not the only one that blames things on Boo Radley.
When people's azaleas froze in a cold snap, it was because he had breathed on them. Any stealthy small crimes committed in Maycomb were his work. (ch 1)
Since no one ever sees Boo, and he is such a mysterious figure, people make up rumors about him. He is an easy target. He does not leave the house. He has no friends. No one comes to visit him. All in all, it makes sense that people think the worst. They do not realize he is really just quiet and shy.
Even though Boo does not leave the house, he does not ignore the outside world. He seems to watch the children and enjoy the antics of his neighbors. In the end, Scout decides that he needs to be protected, and would not understand the people of Maycomb.
