I really like this. I addressed the same question (in a roundabout way) in my own stuff. (The part that you can't have read yet, because it's two years away.) And it's true. Who doesn't laugh at perfect irony? Ok, Remus wouldn't have, but certainly Black would have that kind of self-depricating humor. He came from a family of dark wizards after all. Very nicely done.

Great job!:)

I liked it very much! You made Sirius's character very convincing. I will definitely look out for more of your work.
