Okay, so, I was hanging out just inside the entrance to a secret passageway that opens up onto the corridor near the Slytherin common rooms. I had a bunch of dungbombs in my bag because I was planning this really neat prank to pull on the Slytherin Quidditch team where the dungbombs, which I was going to Disillusion so they couldn't see them, were going to follow them around and everytime any of them said wasn't really doing anything special and, all of a sudden--puff! I'm outside, standing waist-deep in the lake.
I mean, everybody (well, everybody who's ever spoken to Aunt Hermione) knows that you can't apparate on the school grounds. But, somehow, I did it! I mean, I wasn't really trying to apparate at the time... and even if I was, I don't suppose I'd have chosen to end up in the freezing, muddy lake, but still.
Super special super powers, yay! But yeah, I'm going up to my dorm to get changed. I'm all wet. And cold. And kinda mucky.
