Summary of to kill a mockingbird chapter 12

:  overnight after Mrs. Dubose’s death, Jem becomes moody and starts telling Scout what to do, including to act like a proper girl. Calpurnia assures Scout that Jem is just growing up and invites Scout to join her in the kitchen. Things look bright for a while, and Scout starts to suspect that there’s skill involved with being a girl. However, she receives a letter from Dill early in the summer, which says that Dill has to stay in Mississippi with his new father. He promises to return and marry Scout, which is little comfort—for her, Dill is summer. To make matters worse, Atticus leaves for two weeks to attend an emergency legislative session. One morning, Scout and Jem find a cartoon in the paper that depicts Atticus chained to a desk. Jem tells Scout that it’s about Atticus doing things that nobody else will do.Scout heads for the kitchen. Calpurnia asks what to do about church this week. Scout points out that Atticus left collection for them and they haven’t misbehaved in church in years, but Calpurnia invites Scout and Jem to come to her church instead. That night she bathes Scout roughly and supervises Jem. In the morning, Scout puts on her heavily starched dress. Calpurnia leads them to First Purchase, the black church, named because freed slaves bought it with their first earnings. Most people part respectfully and let Calpurnia lead Scout and Jem to the steps, but one woman, Lula, asks why Calpurnia has white children. Jem and Scout want to leave, but the rest of the congregation shuts Lula out and assures the children that they’re welcome.
