Bob was feeling miserable after a difficult morning at school. During a break, he was confronted by Marvin, one of the school bullies. Marvin blocked Bob's path and said they needed to talk. Marvin accused Bob of cheating on his science test by downloading the answers from the school server, even though Bob was not very good at science. Marvin threatened to tell Bob's science teacher what he knew unless Bob paid him fifty dollars. Marvin then walked away, leaving Bob with a racing heart, worried about the trouble he could get in if Marvin reported him.
