I saw her on the steps in front of school and ran over to her. “You stayed after?” She nodded. “I had a makeup test in government. It wasn’t too bad.” “That means you aced it,” I said. Sharma is a total brain, but she doesn’t like kids to say it. Her idea of a bad test score is anything below 110! “Are you walking home?” I asked. “Can I walk with you?” She nodded again. She pulled a bug or something off my tennis shirt. “How was tennis practice?” “Totally weird,” I said. As we started to walk, I decided to tell her the whole story. I had to tell someone! “This kid is my exact twin,” I told her. “But he keeps disappearing before I can talk to him. Today, he was at tennis practice, playing with Jared. But it wasn’t the first time I saw him. I saw him in Max’s pool Friday night. He was swimming right at me!” Sharma laughed. “You make up the dumbest stories.” “No. I’m serious!” I said. “He is my exact twin. In every way. He even wears the same clothes as me.”
