Michelle winces a bit over the impact; watching him get smacked by it is the final argument that she needs to invest in a better binder.

"Ah... yes. Yes, it is." Internally she's caught between embarrassed horror, and a very slight twinge of helpless amusement over the entire thing. And doing her best to look calm and polite through the exchange...though with the way her eyebrows and lips both shoot up, that may be a bit of a lost cause. Still, watching him peel the paper off reminds her to keep a tight grip on what she's managed to catch.

"Thank you, however; for catching that last one. I hadn't managed to memorize what was on it yet, and that would put me at a distinct disadvantage during finals." She pinches the offending piece of paper, to guarantee it won't go pelting anyone else in the face.
