kinda hidden under his leg. About half way through the test chatgpt on his phone starts talking numbers on full volume. Mortified he silenced it almost immediately. My wife is pretty chill so she sorta just acted like nothing happened, but the tension in the room was palpable after that. She said the kid came up last and was shaking when he handed in his test. To his credit he came back and confessed a few minutes after class. This is a college course btw.

Anyway I just thought it was hilarious instant karma.
