"Ah, that," Su said, braking a bit to readjust the way her scarf sat around her neck. The wind kept moving it so that it snared around her right arm which, she thought, would cause a problem if this weren't merely a leisure-flight. Imagine diving for the Snitch during a game, and finding herself held back by an article of her own clothing! "I thought about going home, but then I thought most of my friends would be staying here."
She rolled her eyes. "Yet along comes the holiday, and everyone's gone home after all. It's not terrible, though. I suppose this is my last chance to stay at the castle."
Su didn't add that she also didn't want to go home and have to deal with curfew laws. Even if they'd be difficult for the Ministry to enforce on her personally, as she didn't live especially close to any magical communities or villages. Unless she went out at midnight and explicitly did a bit of magic, she supposed there was no way they'd know she'd broken curfew. Still, just the idea that she was restricted by a ridiculous law in her own hometown...it infuriated Su, and she'd rather just not have to think about it.
"My parents have been sending me things this week, to lead up to Christmas. It's a sweet gesture."
