In Chapter 31 of Harper Lee's To Kill a Mockingbird, Scout's thoughts about Arthur (Boo) Radley reveal a lot about just how much she had learned over the years and particularly at the exact moment standing on the Radley's porch.

Scout had just escorted Radley home, asking him to bend his arm so she could take it, fixing things to look like Radley was escorting her down the street just like any gentleman escorting a lady. After he enters his house, Scout stands before a window to the left of the door of the house and notes how much of the neighborhood can be seen from that window. As she does so, she imagines Radley observing "his children." One of the most significant moments is  when she imagines Radley watching "his children's heart break," which refers the kids' emotions after Tom Robinson lost his trial and was shot trying to escape prison. The second most significant moment is when she says to herself, "Autumn again, and Boo's children needed him," which refers to the moment the kids are nearly killed by Bob Ewell and rescued by Radley. Both of these imaginings open Scout's mind up to understanding just how much Radley cared for the children, just how much he is a kind and caring person he is in general.

Scout's realizations help her fully internalize something she had always been taught by Atticus: "[Y]ou never really know a man until you stand in his shoes and walk around them." Scout further states, "Just standing on the Radley porch was enough." In other words, Scout has learned to see things from others' perspectives and to reject the prejudiced views of others. Scout's realization about seeing things from the perspective of others shows us just how much she has grown up throughout the book and at that particular moment.
