Aunt Alexandra was apprehensive and judgmental towards Boo Radley, viewing him with suspicion and disapproval. Dr. Reynolds, on the other hand, seemed to treat Boo Radley more neutrally, focusing on his physical health rather than his personality or reputation.
Dr. Reynolds spoke to boo cordially, calling him by his name Arthur, as though he knew him. I don't remember an encounter between Aunt Alexandra and boo, but her teaching Scout to behave like a lady under all circumstances caused her (Scout) to invite him (boo) to sit with her and then took him to see Jem.
Scout is surprised because she has always seen Dr. Reynolds as a serious and professional figure who would not interact casually with someone like Arthur Radley, who is known as a reclusive and mysterious figure in Maycomb. The interaction challenges Scout's preconceived notions about how people in the community perceive and treat Boo Radley.
Aunt Alexandra thinks that Atticus isn't 'parental' enough with Jem and Scout.He doesn't make them call him 'Dad' or 'Father', they call him 'Atticus.' He also doesn't make Scout wear dresses like a girl should (in Aunt Alexandra's opinion) because he knows she'll be hanging out with Jem, climbing trees, climbing fences, etc.He talks to his children like he talks to other adults; he treats them as equals which Aunt Alexandra thinks is incorrect. In her world, adults treat children in an authoritarian manner (boss them around), they don't ask their opinion or explain things to them, they just issue orders.
In "To Kill a Mockingbird," Jem and Scout experience prejudice and discrimination when they go to town with Atticus. They witness how the townspeople treat Atticus differently because he is defending a black man in court. Jem and Scout also face harassment and racism themselves due to their father's actions.
Atticus sees the Cunninghams as good people with strong moral values, despite their poverty. He believes in treating them with respect and understanding. Aunt Alexandra, on the other hand, holds more traditional views and looks down on the Cunninghams due to their social status and lack of education. She believes they are beneath their family's social circle.
John Hale Finch, better known as Uncle Jack in "To Kill a Mockingbird," is a bit of a jokester. The children enjoy being around Uncle Jack, but he does not always listen to them and treat them with the fairness Scout feels they deserve. Jack is loyal, however, and Scout believes he treats children with respect. Jack is the brother of Atticus and Alexandra. He is a doctor, and unmarried. Jack is 10 years younger than Atticus.
The people of Maycomb start to treat Atticus and the children with hostility and criticism as Atticus defends Tom Robinson, a black man accused of raping a white woman. They face prejudice and discrimination from the townspeople who disapprove of Atticus taking on the case and for allowing his children to be exposed to such controversy.
Jem and Scout do not brag about Atticus because he has always taught them to be humble and to treat others with respect. Atticus leads by example and does not seek attention or praise for himself. The children understand and appreciate his values, and they reflect his humility in their own behavior.
The golden rule says that people should treat others in the way that they would want to be treated.
