Luna would be chatting with a student in the hallway, her tone calm but firm...

So tell me, why did you think it was a good idea to spray paint the TV, and then throw a rock at it? This "rebellious" attitude needs to be thrown out the window, like you're not "cool" or "funny" when you do crap like this... I'm seriously considering suspending you for one to two weeks!

The student tried not to giggle, but Luna cut them off before they'd start giggling...

Knock it off with that laughter. I'm NOT having it, and I want an explanation as to why you pulled this crap... And if you lie, you're gonna be paying for the damages instead!

The student would stop smirking, realizing the amount of trouble they're in...
