"That kid had your back, that's the one that deserves the free A this year," another commented.
Another said: "That kid respects you. He/She didn't like that the kids were talking about it."
Many commenters were fellow teachers, sharing their own classroom horror stories.
"I had a student come up to me after class to let me know I should stop raising my arms because I had really bad sweat stains in my pits," one woman shared.
While one wrote: "At least he told you. My kids just let me go home wondering why they were acting different."
Others pointed out the fact the note had been written on paper towel, declaring they "lost it" at that detail.
Another said the hole wasn't even big, laughing at the schoolyard "drama" of the situation.
