A Weasley! Oh, your family is wonderful. Septimus is my pupil at home. He is one of the many students preparing to sit their N.E.W.T.S. in my Transfiguration class, which is why I wish I was there, now. Undoubtedly, Professor McGonagall is handling the double duty of my Transfiguration students and her Defense Against the Dark Arts ones. We plan to switch back come next fall. I would say I hope she's not overwhelmed but I'd get a look from her at the suggestion that she could be.
And thank you, Ron. I would rather not know my future if it can be helped. Time Travel is no easy task.
