Reading Passage
On Friday, the class had a big art project. Everyone was painting posters for Earth Day. Mia decided to get her hands dirty and mix colors for her team. Soon, her shirt was covered in grime, but she didn’t care.
While Mia painted, Jake played a dirty trick. He switched two teams’ labels to mess them up. Mrs. Kelly saw it and gave him a filthy look. Jake tried to act innocent, but he was clearly playing dirty.
At lunch, Lily started dishing the dirt about another student’s messy locker. “That’s just dirty gossip,” Mia said, shaking her head. Later, someone spilled paint in the hallway and tried to sweep it under the rug. But the footprints gave it away.
During cleanup, Chris found a paper with rude drawings. “Looks like someone has a dirty mind,” he whispered. Mia replied, “Let’s not drag people through the mud. Just throw it away.” The teacher smiled and said, “Good choice, Mia.”
