At lunch, Scout rubs Walter’s nose in the dirt for getting her in trouble, but Jem intervenes and invites Walter to lunch (in the novel, as in certain regions of the country, the midday meal is called “dinner”). At the Finch house, Walter and Atticus discuss farm conditions “like two men,” and Walter puts molasses all over his meat and vegetables, to Scout’s horror. When she criticizes Walter, however, Calpurnia calls her into the kitchen to scold her and slaps her as she returns to the dining room, telling her to be a better hostess. Back at school, Miss Caroline becomes terrified when a tiny bug, or “cootie,” crawls out of a boy’s hair. The boy is Burris Ewell, a member of the Ewell clan, which is even poorer and less respectable than the Cunningham clan. In fact, Burris only comes to school the first day of every school year, making a token appearance to avoid trouble with the law. He leaves the classroom, making enough vicious remarks to cause the teacher to cry. At home, Atticus follows Scout outside to ask her if something is wrong, to which she responds that she is not feeling well. She tells him that she does not think she will go to school anymore and suggests that he could teach her himself. Atticus replies that the law demands that she go to school, but he promises to keep reading to her, as long as she does not tell her teacher about it.
A voltmeter must be connected in parallel to measure the voltage of a device because objects in parallel experience the same potential difference. A voltmeter is used to measure the electrical potential difference between two locations in an electrical circuit.
