Dear Effie,
Your son has expreced something that I am concerned about. This thing is the most vile thing that anyone has ever said to me.
Your son told that he has a romantic interstet in my baby brother . We need to take this out while we can. I have tried the fear factor on him mayne you should add in some parnetal disappointment and with a dose of that from myself we are sure to bite this is butt before it can become a bigger problem.
Your Favorite Son,
Sirius Black
P.S. Before you write back and tell me this all good for the plan of bringing Regulus into the family I will leave this family because I will NOT be having brother-brother incest in my chosen family. I didnt put up with it before and I wont know.
