What are the stories that have been reversed many times?

A man found the headmaster's mobile phone number from the campus network and sent him a short message of abuse, denouncing the headmaster's heinous crime of occupying the holiday and taking some personal attacks to ease his hatred. At that time, there was no real-name registration system for the mobile phone number, thinking that the principal would be furious when he received the text message, and he could not find out who it was. Must be very wronged. Unexpectedly, the Prime Minister could kick himself in the stomach. Half an hour later, the headmaster actually replied to the text message with approachable wording. He listed the reasons for making up lessons: in order to improve students' grades, the college entrance examination is approaching, and I apologize. I didn't expect my classmates to be so resistant to make-up lessons. Ask my dear friend, what do you think of make-up lessons? Do you have any better suggestions about learning? Welcome my dear friend to comment in his office after class. At the same time, he expressed his appreciation for his bloodline. My dear friend was deeply moved by the headmaster's tolerance. He immediately went to the principal's office for an interview. He was greeted by the confiscation of his mobile phone and a 2000-word written examination. The whole school is closed for a week in informed criticism.
