In "To Kill a Mockingbird," Jem discovers that someone has left gifts for him and Scout in the knothole of the tree by Boo Radley's house. When Nathan Radley fills the knothole with cement, Jem is heartbroken because he realizes that Boo Radley was the one leaving them gifts, indicating that he has been watching over them and cares for them.
At the end of Chapter 7, Mr. Radley (Boo's brother) figures out about the gifts that Boo has been secretly leaving in the tree for the children to find. It is Boo's way to communicate to the children and try to be their friends. Unfortunatley once Mr. Radley finds this out he quickly cements up the knothole. And when asked about this by Jem, Mr. Radley says that the tree was dying when the tree is clearly healthy. Jem starts crying because he realizes that Mr. Radley knows about their "communication" and tries to hide Boo more from the world. He doesn't understand why Mr. Radley is unfair to Boo in this way. This is another example of how Jem is growing up and experiencing life's cruelty and unfairness.
Scout cries after realizing that Boo Radley, whom she once feared and misunderstood, had been watching over and protecting her and Jem throughout their trials and tribulations.
