Why was Scout wrong when she says that they haven't given Boo anything?

Scout is wrong because throughout the novel, Boo Radley has been quietly watching over and protecting Scout and Jem, such as leaving them presents in the knothole of the tree and saving them from Bob Ewell's attack. Despite Scout feeling that they haven't given Boo anything, their friendship and kindness have meant a lot to Boo and have given him a sense of connection and purpose.
