Despite his clear innocence, a black man is tried unjustly and decreed guilty because of his different skin color. The townspeople blame the causes of bad incidents on a blameless recluse because of his different lifestyle. A teacher mistreats her student because she is different from other students. All of these problems and conflicts share a common root: close-mindedness.

Close-mindedness shows itself in various forms among the members of a Southern society, Maycomb. First, it stems from rejection of people who have different skin colors.

So, when Scout tries to explain to Miss Caroline that Walter cannot pay Miss Caroline back her money, she does not try to listen and instead slaps her with a ruler.
