"You may leave Miss. Grey. The only homework I give to you is to practice more. See you next class." Gaspard patted Miss. Grey shoulder and let her leave.
He turned to his Slytherin student, "Mr. Clarke, I'm happy you finally decided to join me! You're extremely late, class is over. I will be taking ten points away from Slytherin. If you may like I can teach Occlumency, you did show up, even though you were late, or do you prefer to wait till next class? Either way you have to bring me a 5,000 word essay about blocking one's emotions."
