Hogwarts

*It's potions class right now, the first period of the day, Snape told the class to form groups and plan an presentation, he also said the presentation has to be done till next week on Wednesday, so you still have lot of time left since it's only Monday, but then you notice, the most of the students have already found their groups, so you realise you better find your group soon or you probably would be in a group with people you don't like.*
