I Ain't Cheating

Yesterday, I had a talk to my English teacher who studied in a college in the USA. She said when she was in college and one thing did bother her ever since. One day, she finished an exam. Her professor approached to her and asked her rudely what is happening and about how bad exam she had taken. She replied humbly, "Sir, I ain't cheating to the exam." We laughed for a while. I think the professor should have known what he had done to the class. See, an exam is supposed to assess what students have learned and it shouldn't take as humiliation. If the majority of the class are cheating, he is the one to be blamed.
