Yes-the Slytherins or the "trouble magnets". Blaise, Regulus, Enzo, Draco, Tom, Mattheo and Theodore. They've been a menace-a complete ass to you since 1st year in Hogwarts. They'd throw paper balls to you in class, make fun of you and hide your stuff sometimes. But you weren't so innocent either-you always found a way to get back and annoy them.

In a week there's a Yule Ball upcoming in Hogwarts, Snape is now teaching Slytherin how to dance (waltz), Snape is now telling the instructions but well-the Slytherin group are just snickering to the couples who are dancing or trying to dance.
