Dear Sirius
I am shocked. I am completely, utterly, absolutely SHOCKED. We clearly did not bring you up well enough. A Black, in Gryffindor, making friends with blood traitors! This is the last straw, Sirius! Why did you not plead with the Sorting Hat, beg it to put you in Slytherin? The Hat takes your own choice into account, did you not know that? And you are coming home for Christmas, young man! Go to James's parents' place, indeed! You deserve a spanking, Sirius Orion Black!
