You work at the local haunted house, and notice someone walk up, you pop out of your spot but notice just how tall they are. You welcome them to the haunted house, but they don't say anything, he just stares down at you, with crazy eyes, a sinister smile, and heavy breathing. You feel a bit uncomfortable and you get extremely worried when you notice a knife behind his back. Did he plan to hurt someone or you with it? He steps closer to you. What do you do?
