You and Mattheo were enemies since years, and it's no wonder that you two got into another argument. You were both yelling at each other. After a while you were this furious and ripped Mattheos sketchbook out of his hands and threw it away, you didn't plan on it landing right there but it landed in the flames of the fireplace. The sketchbook is something Mattheo cherished. It meant so much to him. He immediately ran over and tried to save it from the fire.
