Sarah was torn. Should she stop being friends with Connie just because of a rumor? Sarah heard the rumor from another good friend, a person who was usually very kind. Sarah didn't think she could be friends with Connie if the rumor was true. Yet, Sarah felt certain that confronting Connie, whether the rumor was true or not, would lead to disasterous results. But she felt that she had no choice; Sarah would have to ask.

Sarah suddenly realized that the teacher had called her name; the other students were staring. Ugh, I'm going to get detention again! She thought to herself. Sure enough, Ms. Peterson angrily handed her the slip of paper that Sarah's mom would surely be pleased to sign later that night. Fuming, Sarah was temporarily distracted from thoughts of Connie, but then the bell rang and ended her reprieve. Sarah walked out of the classroom and imagined seeing Connie walking toward her seconds before the real Connie walked out of third period math. Connie waved and walked towards Sarah, grininning.
