"Class dismissed."
"Boom!"
Professor Li is already over 50 this year, not far from retirement, but even at this age, he is still quite spry.
But in just a moment ago, he couldn't help but wonder if he was experiencing dementia.
Didn't this class seem to be full of students just a second ago?
How is it that he said "class dismissed," looked down to arrange his teaching materials, and the whole classroom was suddenly empty? So clean as if no one had ever attended class.
Adjusting his black-framed glasses, Professor Li had to mumble to himself, "Did the entire class skip? Should I just fail them all?"
A closer look revealed there was indeed still one person left, but this student had bandages on his leg, looking injured.
Professor Li thought he'd better verify: "Student, was it just you and me in this class?"
Lu Ming shook his head, "No, Professor Li, the class was full just now, they only left after you said class dismissed."
