Step-by-step explanation:
People don't get along with each other because of various factors such as segregation, discrimination, poverty, and different cultural backgrounds. In Harper Lee’s novel 'To Kill a Mockingbird', Scout explains that people who have never experienced the negative impacts of these factors may not understand why it is difficult for others to get along. For example, she mentions the violence and injustice faced by African Americans, which creates divisions and tensions in society. This highlights the importance of empathy, understanding, and addressing these societal issues in order to foster better relationships.
