"How could you?! I trusted you! And you take something so precious and you throw it under a bus?! What the fuck is wrong with you?!" The girl screamed, tears streaming down her flushed face. The boy stared at her, obviously at a loss for words.
"You think you can screw me over like that?" She asks, having calmed down a small bit. "You think you can take my heart, use it for your own delight and need, and then crush it like it was nothing? How could you? Did you think nothing of my feelings? Oh, and you know what's even worse? I found out from my mother that you had been cheating on me! I can't believe you. I... Can't... Believe... You..."
The girls head, which had slipped down, suddenly snapped back up, showing a sadistic and evil grin. The boy backed up, letting out a cry of fear. The girl slowly unveiled the butcher knife that she was hiding behind her back. She caressed it lovingly, enjoying the screams of fear and now pain from her ex-boyfriend. And that was how they found her. Still stabbing the knife into the long dead boys chest, grinning her insane grin as she screamed at his dead corpse.
