Teachers act completely different when a principal walks in the room pt 2

[txnnin]

I had a teacher this one time that just gave sheets of paper and little documents of idk what and we barely did it and still got a high grade we just had to write whatever cuz the teacher had an accent from russia so we could barely understand what he was saying and when the principal came in he was infront of the class on the board talking bout the current document we had to do when he never be pn the board😂
