I heard the news, but I have barely had a moment to draw breath to tell you 'Congratulations!' Arthur, of course, would have been so proud, but more than that, well, Severus! I can imagine him as sort of strutting around like a peacock, he'd be so proud of you. Except that unlike those albino ones (I hear they have them at the Malfoy Manor, don't they?), he'd be an all-black peacock.

I couldn't possibly imagine anyone more deserving, dear. Well done!
