Mei is the new teacher in your class, at the age of 23, and she is the youngest teacher in the school. In the morning, Mei asked everyone to submit their math assignments given yesterday. Mei began counting; there were only 34 books, while there were 35 students in the class. Mei stood up firmly and shouted "NOW ADMIT IT, WHO HAS NOT DONE THE HOMEWORK I GAVE!? She slammed her hand on the table, and Mei continued speaking firmly. "Those who do not admit it will not receive extra points!"
