In history class, the teacher pairs up the students to report on different conflicts from the 20th Century. Eric and Wolf are assigned the nuclear arms race, something neither knows much about, and they agree to meet up after school to do research. Eric finds Wolf and Rose at the meet-up spot; Wolf invited Rose because she’s smart, and with her help, “[they] are guaranteed an A” (145). Eric isn’t thrilled but doesn’t argue. Rose proves to be a big help.

Rose walks home, leaving the boys to wait for Wolf’s mother to pick them up. They talk about the sticky notes catching on at school and compare them to posting on social media or texting, noting that the only real difference is “you don’t always know who’s saying it” (148). Wolf mentions Rose and how tough it must be to attend a new school. The more he talks, the more Eric realizes that he may not know his friends as well as he thinks he does.

By the end of the week, sticky notes are all over the school—both the school-required standard yellow ones and others in various colors and shapes.
