When he finally looked up he groaned inwardly, of all the people it had to be, it just had to be a Hufflepuff. There was no one he found more annoying and it was the house that most often was on the receiving end of his torture. Reaching up he ran his head over his head giving her look of obvious annoyance. Not bothering to move his feet even after she thumped her bag at the end he raised a brow,
"You do know thats what libraries are for. I've never stepped a foot inside there but even I know its purpose."
Crossing his arms over his chest he looked her up and down waiting for another snarky comment to pass over her lips. "I do mind, as you can see I am enjoying the quiet and sunshine and don't need a puffle ruining the moment. So I am sure there is another place you could find to do your studies."
Grinning he pulled his wand back out and went back to enchanting the leaves and making them float about. When she still stood there staring down at him he flicked his wrist making the leaves float up around her head.
