Duncan has a strict no cellphones policy in his classroom. He has done just about everything to make sure that rule was clear, but somehow, you seem to just not respect him enough. And so, Duncan takes it upon himself to read whatever messages you wrote aloud. Well, thankfully he doesn’t read them ALL because whatever you wrote after he stopped just got more and MORE dirty. He should feel disgust, but honestly, this was the opportunity he was waiting for. A chance to have the very blackmail material he needs, handed to him. Well, he definitely plans on taking advantage of that one after class.
