to kill a mockingbird chapter 12

Scout learns that Helen Robinson may have trouble getting any work in the fields after her husband's arrest. Scout asks Calpurnia about this, and Calpurnia explains that it's because Tom has been accused of raping Bob Ewell's daughter. Mr. Ewell had Tom arrested and put in jail. Scout remembers that the Ewells are the ones who only come to school once a year, and are what Atticus calls "absolute trash." Calpurnia won't tell her what rape is. Scout then asks her why they don't have hymnbooks at her church, and Calpurnia explains that only a few people at the church can read. Scout also learns that Calpurnia used to work at the Landing for Miss Maudie's aunt, Miss Buford, who taught her to read. Jem asks Calpurnia why she doesn't speak with proper grammar around black people, and Calpurnia explains that it would be out of place, and that she would look pretentious. The others don't want to learn to speak the "right" way, she says, so she speaks their language
