^^Oh, trust me, I wouldn't abuse it. Again, this wouldn't even occur in her O.W.L years at the very least, and if she managed it, she wouldn't use it like that. And I'm pretty sure that if Hermione weren't too busy saving Ron and Harry all the damn time, she could have managed it too.
I enjoy the debate, but I don't want to overstep or anything, it is up to you. :3
