Olly was not really surprised that there was a real fwooper. It was the subject of the class so that would only make sense, right? He was a bit worried right away, because of how the sound can drive someone insane and whatnot. But the professor had brought earmuffs and they were practicing the silencing charm so there was really nothing to worry about. Olly went and grabbed a pair of earmuffs for himself, a pale purple one. They were very soft and comfy against his ears.

Silencing charm. That wasn't too hard. Olly knew that one and he had performed it before so he wasn't too worried. He didn't even feel the need to practice. He knew the incantation: silencio. And the wand movement was just a jab. Easy. He just wanted to get to the exciting part of the lesson. Were there more fwoopers? Were they all going to perform the charm?
