You spot the huge, neon-pink backpack—it belongs to Lissie, the new kid. It's so big it looks like it could easily hide the entire platter. You decide you need to look inside. You need the cupcakes back for the party! You carefully, slowly, pull open the zipper just an inch. You peek inside. It's dark, but you can see the outline of something round and shiny. You start to pull the zipper wider— "What exactly are you doing?" a deep voice booms behind you. It's Principal Sterling! He was walking down the hall and saw you with your hands on a backpack that wasn't yours. You freeze. Principal Sterling looks stern. "This is not how we solve mysteries, young detective. If you suspected theft, you should have told Ms. Lily, not invaded someone else's property." You are immediately sent to the office. The Valentine's Day party is happening without you. Instead of eating cupcakes, you have to write a two-page paper on "The Importance of Respecting Others' Belongings." The cupcakes are found much later by the janitor in the art closet. No one will admit to hiding them. But the class enjoyed the Valentine's Day activities still, while you missed the party. The End.
