Hey Pandas, What's The Worst Punishment You Have Gotten From A Teacher?

My German language professor always lowered my grades from paper tests, homework, cus she thought I was so good that I actually should have tried even harder- cus it wasn't good enough in her opinion for me to get the A grade. Always said "very good, but should have written *so and so* better'! 🙄🤷🏼‍♀️ But I think it was her revenge cushion she heard my class giving her a nickname "squirrel" and I laughed hard!!! She heard that.. ☺️😇
