I Turned Out to Be a Rule

Hey, I can't sleep well at all. What kind of question are you asking me to do? It would be okay if you ask me what one plus one equals. I walked to the blackboard, shaking my head, and looked up. 1+1=? "You don't think of me as a human being, do you?" I wrote a big 3 on the blackboard with all my strength. After I finished writing, I broke the chalk in half and threw it away. Suddenly, the whole class burst into applause, and Teacher Feng looked at me in disbelief with Shui Wangwang's big eyes.
