"Stuck up harpy?" Keith said. "I never called you that! You've never been anything but good ol' Liesl. C'mon boss, cut me a little slack here?"
Liesl rested her chin on her arms, obviously waiting to see what would happen.
"Alright, no big deal," Keith said, shaking his head and turning back to Lucy. "You really should think this through," he said, edging his foot towards the coats as he spoke. "I am a prefect after all. I don't really know what I'm allowed to do, but hey, I could probably get you in trouble." He smiled and gestured with his hands, trying to keep Lucy's attention on him and away from the floor.
"I'm surprised you three engage in such an activity right under Professor d'Eath's nose. My experiences have taught me that it would be prudent not to horseplay in his class...or has the Professor become less strict than I remember?"
Keith couldn't see who was speaking, and he didn't recognize the voice, but that didn't matter. "Exactly," he said, motioning towards the general area the voice came from. "You should listen to her Lucy, really I mean it's almost like - haaa!" He planted his foot on top of the coats and yanked it backwards, attempting to send them sliding under the table and out of range before Lucy could do anything about it.
