That the Ewells have been a disgrace to Maycomb for 3 generations not doing a single day of work.
In "To Kill a Mockingbird," Atticus reveals to Scout that the Ewells are a poor and troubled family with a history of wrongdoing. He explains that the Ewells are considered low-class and dishonest by the community. Atticus also emphasizes the importance of understanding their circumstances and showing compassion towards them.
Scout's punishment for trying to help Walter is a reprimand from her teacher, Miss Caroline. The class laughs because they find it amusing that Scout doesn't understand the social stratification and expectations of the community, as well as the unwritten rules about how the Ewells are regarded compared to the Cunninghams.
When Scout says Maycomb gives the Ewells "the back of its hand," she means that the community looks down on and mistreats the Ewell family, considering them inferior and unworthy of respect. The Ewells are marginalized and neglected by society because of their low social status and poor reputation.
The only people who were present during the attack was Arthur (Boo) Radley and Bob Ewells.
When Scout says the Ewells live as guests of the county, she means that the Ewell family receives special treatment because they are poor and seen as societal outcasts. They are allowed to break the rules and receive leniency from the townspeople due to their disadvantaged circumstances.
Atticus reads the book "The Gray Ghost" to Scout and Jem the night of Bob Ewell's attack. This book is one of Scout's favorites, and she finds comfort in listening to her father read it.
In "To Kill a Mockingbird," Scout describes Burris Ewell as having a "cootie nest" in his hair, with a "squashed pumpkin" of a face. She also mentions that he has a "rank smell" and "filthy" clothing.
Because he thinks he can never force Scout to leave without him taking Scout home himself, if he does take her home he will miss Bob Ewell's testimony, plus Scout will insist to stay anyway (being an inquisitive girl she is) , so he has no other choice but to let Scout stay and tell Rev. Sykes that she's only 9 years old and therefore won't understand what's going on anyway; particularly the profanity and cussing by the Ewells.
Scout asks Atticus if he and Walter Cunningham Sr. are poor, to which Atticus responds that they are not. Scout then wonders if the Ewells are considered white, leading to a discussion about societal issues and background.
Scout learns that Burris Ewell is from the Ewell family, who are known to be poor and disrespectful. Burris is rude, only attends school on the first day, and also has lice, which causes Miss Caroline to become upset. Scout realizes that the Ewells are considered outcasts in Maycomb society.
Ms. Caroline Fisher doesn't understand the social structure of Maycomb: the Cunninghams and Ewells.
Bob Ewell was working against Scout in To Kill a Mockingbird. He held a grudge against Atticus Finch and targeted his children, including Scout, in his attempts to seek revenge. Bob Ewell was responsible for accusing Atticus's client, Tom Robinson, of a crime he did not commit.
