Jem has grown in Part 1 of the novel because at first, Jem thought that Boo Radley was creepy and scary. After Radley left the gifts under the tree, Jem realized that Boo Radley was a normal person who stayed indoors because the outside world was unfair.
Another example of how Jem grew more mature was when Dill ran away from home to go to Jem and Scout. Jem realized that Dill’s parents would be worried because their only son went missing. Jem tells Atticus about Dill because he didn’t want Dill’s parents to be worried.
