Upset--no furious, THAT was the only way to describe the 11 year who had only recently begun pacing the corridor.

Luckily she was on the outside of the castle...very far away from anything she could possible get her hands on and break. Every few seconds her fingers twitched, itching to grab at something. This was a tell-tale sign that a tantrum wasn't very far behind. Merlin she hadn't had one of those in months! Before she got here she was finding that there was less and less need for those but now, oh now she just wanted to scream and break things and hit stuff; anything to relieve the tension that was building up.

Why were older kids so stupid and Professors so mean?! See, this was why she went around causing mischief. They deserved it for one reason or another. This was also why she didn't like anyone older than 11--with a few exceptions of course.
