This Monday, I was in the middle of turning in my Millard Fillmore Term & Outline in my APUSH class. And I noticed 2 piles on the desk instead of one. One for Millard Fillmore and the other for Franklin Pierce.
I turned to the homework board, and it said:
Fillmore (Mon)
Pierce (Wed)

I was like:
"Mr. Teacher, why are their two piles?"

He says:
"They're both due today. I said something on Friday."

I felt like screaming:
SO WHY DIDN'T YOU PUT IT ON THE BOARD?!

Then there are teachers who stress a due date to the point you stress yourself out and stay up late doing it, and you make it perfect, and bring it in that morning and you ask:
"Hey, aren't you going to collect this? It's due today."

And they're like:
"Ummm... yeah I'll collect that sometime withing the next few weeks."
