I'm sure foolish Gryffindors expect congratulations. However since neither of us is a Gryffindor, I'd like the chance to speak with you and check for any hexes that might have convinced you to do such foolish thing.
In the event that none exist, I'd like to mention that I did tell you that the boy was marking his territory long ago, when you tried to turn things on me, in which case you owe me an apology.
Moreover, you should apologising for forcing me to be near so many Weasleys and Potters. It's bad enough that I have to deal with James, and now you as well. Really what have I done to deserve this?
Finally, even thought I object to your choice on the grounds that he's a Potter, not me and an idiot, should you require a witness that won't try to kill you, I am available. Do give me notice since I shall have to ensure that I have the best robe, taking the spotlight from all. Not that it's hard considering your new relatives are Weasleys and Potters.
