Katrina decided to accept the Professors explanation, but still was a bit sour about his thought of being in Slytherin needed an explanation. Though, she understood what he was saying. She forced a smile and nodded as if to say, I understand.
When the Professor asked her about her family, Katrina finally had a genuine smile. "I have a wonderful family. Both of my parents went to the original Hogwarts, and they were both in Slytheirn; as well as my big brother, Thomas. My family is very wealthy, my mother has never had to work, and my father only works when he feels like it. It's mostly from an inheritance from my grandparents." She frowned slightly; the fact that she came from a family with money was something she didn't like to talk about. People always treated her differently when they learned that she was "privileged". She couldn't remember if she had even told Faciln about it, but doubted it. She really had no idea why she had even told the Professor. Obviously, he was a good person, in order for Katrina to feel obliged to tell him the truth. Although, there were bits of her family she was going to leave out. There are things that she was told never to tell to anyone at the school, and she had promised her parents she wouldn't. So she smiled and added, "Instead of sending me to a..." Mudblood was the first word to come to mind, but Katrina had seen first-hand how this phrase angered people, "Muggle school, my mother home-schooled me. So I've known of the Magical World extensively since I was born."
She smiled again, and looked up at Faciln. He looked so happy up there on his new broom. She was so happy for him.
