Dear Mother,
I have written to Aunt and Uncle to apologise as you instructed. Of course I realise how lucky I am that you let me come back to school without proper punishment for my behaviour at the party, and I assure you that I’m very grateful for your and Father’s graciousness.
I’m sorry that the Healer couldn’t find anything wrong with me.
I’m sorry that I fainted when Sirius wouldn’t have, even though he's shameful and
I’m sorry that I’m not as brave as him.
I'm sorry.
I know that I can't even begin to understand how embarrassing it must be for you to have such a weakling for a son. But I'm not weak, Mother, I'm not, and I shouldn't have been sorted into Hufflepuff, or, or-
I promise that I will do everything I can to overcome my inadequacy.
Your obedient son,
