Here are the rules from his post:
It's quite simple. All you have to do is choose which two characters would be YOUR best mates at Hogwarts. You can use any student characters from any book.
After you choose your mates, then, all you have to do is write a fun little piece on why and what kind of trio would you be. It's that easy.
Have FUN with this. Let's keep it between 300-350 words, so we can all read each others work. Sound COOL?
And here is my entry:
I write this letter hoping you will read it on the train.
First, let me tell you how proud I am of you, my son. I know you will be an amazing wizard.
I am so excited for you and for all the new adventures you will experience at Hogwarts.
As for your House, the sorting can be frightening.
Let me share my own experience to help alleviate your concerns.
If I had been incredibly brave the Sorting Hat would have chosen me for Gryffindor.
If I had intelligence to spare, Ravenclaw.
If I was completely mental, Slytherin.
But, I was none of those things.
I was from an average wizarding family who taught me to be a good student, loyal friend, and to be honest and fair.
I was chosen for Hufflepuff.
While at Hogwarts I saw great things, some terrible, but great.
Good friends helped me through those turbulent years.
In my second year I met Hannah Abbott when she was sorted into our house. She was short on self-confidence and easily flustered but she was a good friend to me and always there when I needed her.
In my first year I met the handsome Cedric Diggory. He was in his second year and had already distinguished himself as an excellent student and athlete, but he was modest, fair-minded and a fierce, fierce friend.
You already know how we lost Cedric. How his tragic murder would compel his classmates to form an army and fight against Voldermort and his Death Eaters, to fight against evil, to fight for those that had sacrificed everything.
Without my friends I might never have had the strength to fight. I’m proud of them, and myself, because we made a difference.
It is my wish that you and your classmates will always be able to look up at that beautiful Hogwarts Castle and understand and appreciate all that was lost and found to secure your future.
Good luck. Study hard.
With all my love, your mother
