Summoned to the office

During Algebra II, the intercom calls Charlie Decker to the office. He leaves the classroom, feeling his stomach tighten and experiencing paranoid thoughts about Mrs. Underwood pursuing him. He stops in the bathroom to eat Ritz crackers and thinks about Sandra Cross, recalling a school dance where her jeans unzipped, revealing white panties. He also worries about being sent to Greenmantle Academy.
