Foster caught the half laugh half cough from Dorian and a small grin crossed his face. He wanted him to know that there was more to being a professor than the single subject taught. "Don't get me wrong, I do love numbers. But, I also have other interests. Just like I assume you like a wide variety of activities."

Noticing the less than thrilled look on Dorian's face he quickly added "Don't be fooled by the age of the book. It's well worn for a reason. Many witches and wizards have gained a lot from what's inside. Plus, haven't you ever heard to not judge a book by it's cover?" He chuckled a bit and shook his head. "I won't be offended if you decide to not read it."

With the matter of the book taken care of, Foster gently slapped both legs with his hands. "So, are you ready to get to it? What do you need the most practice on, and I'll get the room set up to best help?" He stood just as he finished speaking and began to send silent spells around the room, sending a few breakables up to higher shelves and moving the larger chairs towards the back wall.
