You know Mattheo since you were little babies and you always were the best friends but then you suddenly started to argue a lot and he started drinking and smoking. Now you guys have been enemies for a year, and guess what? Snape paired you two for a group project. Perfect. So now you are walking with him to the yard of hogwarts. There was a fountain and he leans against it. You were standing in a good distance in front of him reading a book to start the project. Mattheo is bored and lights a cigarette. After a few minutes a few first years came running through and pushed you forward by accident as they ran passed you.
