Shrugging his shoulders, Sirius reached around to pull the closest chair up to her desk. Upon doing so, he sat in it backwards, and leaned his elbows on her table. Women loved confidence, right? Well, Sirius had a ton of it, enough to share actually. "Well I'd have said Sirius Potter, but then you'd never figure out who I really am, since Dumbledore won't list me as that in any of the school records. Which is pretty bullocks, since I'm not even a Black anymore." If Juliette knew anything about the wizarding world, she'd know how strict and annoying Blacks were. If things went Sirius' way, she wouldn't be an elitist pureblood, and he wouldn't have to worry about any of that. Being pureblooded was such a chore, anyways.
Sirius tilted his head to the side, and grinned. "Now now, Miss. Class is over for the day - you can't be fooling me. And I'd know, since I'm usually the first one out of there." Of course, all of Sirius' confidence exploded into cockiness. So far it had worked for him, but he'd known many others to get screwed by it. "I donno though, what exactly do teaching assistants assist with?" Sirius clicked his tongue and smiled again. "Ancient ruins though, really? There's nothing exciting there! It's just a bunch of boring numbers and pyramids."
