Eh, keep it on...

"Eh, I'll keep it on. I have thin straps underneath, so yeah," you explain to your classmate.

"Yeah, but it's warm in here. I don't think he'll really mind," your classmate suggests.

"Maybe, I don't know," you mutter quietly.

"He seems like a cool teacher. Besides, you have a good grade in this class, so he'll probably let you slide."

You consider what your classmate has said. You think about whether or not to take your cardigan off or not, again. Should you, or should you not? The sleepiness isn't wearing off anytime soon, and it is getting a bit too warm in this classroom.
