An Apology Would Have Been Nice

Lauren Soth, an emeritus professor of art history at Carleton College, describes one of his worst mistakes in nearly forty years of college teaching.
 
As the eraser arced through the classroom, I realized with a petrifying shock what a horrible mistake I had made. The student was sleeping in class. She was too far away for nudge or comment. Grabbing an eraser from the blackboard chalk tray, I had lobbed it upward, expecting it to fall gently in front of her or in her lap. She would wake up, everyone would chuckle, class would continue. Such was my fatuity. And now I could see that the eraser, in its arched trajectory would land right in her face. It did exactly that, knocking her glasses off, startling not only her but the entire class.

Thirty-five years later this student signed-up for an alumni cruise that Soth was hosting.  Read what happened here.
