When walking to the business section of Maycomb, Scout and Jem encounter Mrs. Dubose. Each time they pass by, she shouts at them.
"Don't you say hey to me, you ugly girl. You say Good Afternoon, Mrs. Dubose!"
As they make their way through the business region, Scout spots the baton that she has been eyeing on for a while considering her ambition to join the band in high school.
With his twelfth birthday money, Jem was generous enough to buy himself a steam engine and Scout's twirling baton.
The things that Mrs. Dubose would say would sometimes anger Jem. However, when she states that their father is not any better than the trash he works for, Jem loses his temper and takes the baton that he bought Scout and cuts down every single one of Mrs. Dubose's camellia bushes.
In addition, Jem snapped Scout's baton in half and kicked her because she kept shrieking and did not stay quiet.
As a result of his actions, Jem's punishment is to go to Mrs. Dubose's house and read to her everyday
When Jem goes to Mrs. Dubose's house, Scout accompanies him.
During each session, the two endure Mrs. Dubose's abuse. A few weeks after Jem's punishment ends, Mrs. Dubose dies.
When Atticus returns from Mrs. Dubose's house one day, he returns with a small candy box for Jem from Mrs. Dubose.
When Jem eventually opens up the box, he finds a single, white camellia. He then throws the box into the fire, but keeps the camellia...
Atticus explains how Mrs. Dubose was addicted to morphine, which is why she was ill and cranky, in which reading was a way for her to help with her addiction.
