Dinner had been going for quite a while, and Airy was waiting in a classroom on the second floor before she attempted to make her way into the Great Hall. Dinner always made her nervous, it wasn't that she was bad around people, it was that one year she had had a mini panic attack in the Entrance Hall, and avoided the place like the plague ever since. Except when she had to, such as dinner time, when she was forced to cut through the Entrance Hall to get food.
Normally she'd have gotten in early and sat down before anyone else was around, ready to eat and be up before anyone else had gotten up, but she had been stopped by a professor who had scolded her on not attending lessons for nearly half an hour, and by the time she had been let free, Dinner had just started and the entire school was heading down the steps to get their food.
Airy had let herself be carried down the hallway with the swell of people before finally ducking off into a side classroom and kicking her feet up on a desk, resting and listening to the stampede of feet that announced that people were still heading downstairs. Finally it quieted and Airy stood up carefully, going to the door and peeking her head out. It seemed quite deserted, and the smell of dinner was wafting up the stairs towards her, making her stomach growl.
Now was her chance!
Airy took off down the hallway, bolted down a couple stairs, around a corner, and bolted down the Entrance Hall stairs, when quite suddenly she saw a girl, covered in mud heading up the staircase, but Airy was going far too fast, and was on a collision course with the girl, letting out a shout of warning, Airy flew down the stairs directly towards the girl.
