[Angus is just coming back from the library, a pile of books stretching up higher than his face, completely blocking his view of anything in front of him. But when he reaches his door, and he's sure it's his door, he counted the floors and doors on his way, but there sure are a lot of... broken lockpicks piled up on the floor by his feet. More than that, there's someone fussing with his door, as far as he can hear, and, still holding the books before his face, he fishes out his wand from his pockets and points it past the books at whoever it is that's trying to break into his room.]

I don't know who you are, but I must warn you, I have a, a great mastery of wizardly magicks and spells! And you've been caught red-handed! Please step away from the door!

[This might be more threatening if he wasn't obviously blocking his own view of the would-be thief with this huge pile of books, and his voice didn't still have the high squeak of a ten-year-old, and his wand didn't have a huge cutesy star at the end of it.]
