When schools were closed owing to the coronavirus outbreak, the English teacher Petria May did the most natural thing she could think of: she assigned her tenth-grade class to read Albert Camus’s novel “The Plague,” which describes a quarantine during an outbreak of disease. Plus, a short story by Peter Cameron. In “Memorial Day,” a teen-age boy is forced to spend a beautiful Memorial Day with the two people he really can’t deal with: his mother and his new stepfather, Lonnie, who’s so young he’s sometimes mistaken for the narrator’s brother. The boy is talkative in school, and he writes letters to pen pals in prison, but at home he hasn’t spoken a word in months. Noah Galvin reads the story, which was originally published in The New Yorker in 1983.
