This is Scout's perception of the world from Boo's eyes. She stands on the porch and imagines the world from his perspective, recapitulating the major events of the book as Boo would have seen them. This passage serves as the epitome and culmination of Scout's character development and the entire book, as it shows both how Scout has finally understood the lessons Atticus has tried to teach her from the beginning by seeing the world sympathetically from another's perspective and the books' moral epitome, the idea of good and evil coexisting in humanity, and that stepping in others' shoes is the only way to really see a person. Once you see them, they are more often than not very nice. Remember, Boo was once a monster, now he is a protector and endearing character to both Scout and the reader.
ANALYZE: A boy trudged down the sidewalk dragging a fishing pole behind him. A man stood waiting with his hands on his hips. Summertime, and his children played in the front yard with their friend, enacting a strange little drama of their own invention. It was fall, and his children fought on the sidewalk in front of Mrs. Dubose's. . . . Fall, and his children trotted to and fro around the corner, the day's woes and triumphs on their faces. They stopped at an oak tree, delighted, puzzled, apprehensive. Winter, and his children shivered at the front gate, silhouetted against a blazing house. Winter, and a man walked into the street, dropped his glasses, and shot a dog. Summer, and he watched his children's heart break. Autumn again, and Boo's children needed him. Atticus was right. One time he said you never really know a man until you stand in his shoes and walk around in them. Just standing on the Radley porch was enough.
