In a Public Class, a Student Replaced My Courseware with a Confession

In an open class jointly organized by key schools in the city, my teaching PPT was replaced with a "confession". "The first crime is that he is not worthy of being a role model." "The second crime is that he tried to obtain a senior professional title through bribery." I said to my husband who came over: "Explain it to me." Without saying a word, he slapped the man. "Where did the bastard come from? He was born but not raised by his mother!"
