how has jems reaction to the gifts in the tree changed?

Mr. Radley, who plugs up the hole, and all the other adults discourage Boo's interaction with the children, but Jem feels great sympathy for the man, reflecting the beginning of his passage from childhood to adulthood. When the conversation with Boo ends, so do childish games, and Jem must mature. Standing alone on the porch, Jem stands on a threshold between indoors and outdoors, between childish freedom and the inside civilized world of adults. In this quiet, reflective, sad moment, we don't know what Jem is thinking, but perhaps he is mourning the last days of his own childhood as much as the unfair imprisonment of his mysteriously detached new friend, Boo Radley.
