Sorting Ceremony. Probably the best and worst thing for Hogwarts students. Best for the reason you make friends and gain another family. Worst because whatever house you are put into will define you for the rest of your life.
This easily gave me a bit of nerves when I got my Hogwarts letter. My mother was from a line of Hufflepuffs but was placed in Slytherin. My father, all I know was that he was a Gryffindor. That's all my mother ever told me and my brother. She has refused to tell us anything about him, not the family name, nothing.
My twin brothers name was called. Our best friend since we were children, Teddy Lupin, was sorted into Hufflepuff. I've stood by both my best friend and now brother being sorted into their house.
I watched as the sorting hat was placed on my brothers head. I grumbled for a few seconds then called out, "Gryffindor!" The Gryffindor table erupted into cheers and claps for a few moments as my brother walked over. He cast a smile at me before sitting at his new table.
My turn. I walked up to the stool, faces the rest of the school and the sorting hat was placed on my head.
"Ah, another one of you. Alright, alright." The hat grumbled, "hmm, brave like a Gryffindor, loyal like a Hufflepuff, resourceful like a Slytherin." I sat still patiently as the hat grumbled to figure out my house. "Okay! I see! Well then, let it be... Slytherin!" The hat finally called out.
The Slytherin table erupted in applause at the new house member. The hat was taken off my head as I stood and walked over to my table. I don't believe that twins had ever been separated into two different houses in all of Hogwarts history.
I looked over at Gryffindor table and see my brother with a shocked expression. We'd never imagined being split, especially with a house rivalry so intense.
Teddy, my brother and I made a promise that night. A promise that no matter what, our houses wouldn't get in the way. House loyalty didn't count if it were playing against the three of us. It rarely existed. More or less during quidditch matches when our houses versed each other.
Our mother was happy with it. House rivalries didn't get in the way of family. Andromeda, Teddy's grandmother, was also pleased to hear it too. Occasionally other students would give us a hard time because of Teddy and my brother hanging around a Slytherin. It typically didn't bother us, we just ignored it half the time.
That's how the three of us dealt with the whole house rivalry. Throughout most our Hogwarts years. That was till I learned about my tied prophecy with my brother.
