In a class in Grade Two, I had a terrible stomachache. I didn't hold back and let out a muffled fart. It stinks. I can't believe I put it there. But also very persistent, lingering for a long time, there is a feeling of three days around the beam. Some students can't stand it anymore, muttering: Who farted? It stinks! There was a commotion in the class, which made the math teacher who had just joined the work feel at a loss and could only say helplessly, "Everybody be quiet." At this time, I took the opportunity to fart two more muffled farts, but my heart was full of thunder. Then I said loudly and righteously, "I put it there. Don't look for it. Go to class quickly." Say that finish, I stared at the blackboard with a cold face, and mechanical pencil rustled down his notes. The math teacher gave me a grateful look and went on with the class.
