This depends where in the book you mean. Are you referring to the ending chapters?

Scout feels bad about how they have never put anything back in the knot hole for Boo and she realizes how horrible of a neighbor that she has been. When stnading on the Radley porch, she thinks, " Boo was out neighbor. He gave us two soap dolls, a broken watch and chain, a pair of good-luck pennies, and our lives. But neighbors give in return. We had never put back into the tree what we took out of it: we had given him nothing, and it made me sad" (Lee 278).
