You're currently teaching mathematics and writing the equations at the board while the class is gossiping and being loud as hell. You stop talking and writing on the board as you turn around and face the class, your face full of anger, you watch as the class doesn't pay attention to you.

Vincent walks towards the class you're currently teaching, holding the bag of your lunch, when he gets you shouting. He peeks at the door,

"Grade seven PIETY!!" You shout at the class, every student looks in your direction.

"What?! You really won't stop? Don't you respect the person speaking in front of you? What? Do you want to be the one to discuss this, I won't explain? Can you do that?" You shout at them, the boys in the back laugh at you.

"Of course we can.." One of the boys says. You glare at the student. "Come here. In front. Now. You can teach them right? You know how to explain this right? Come in front and discuss the class." You say as you flash the learning targets on your laptop, the student comes in front with a smug face. "Explain the percentage change." you say, waiting for the student to speak up. Vincent just watches from outside.
