You are sititng on couch, watching tv with holding remote, you feel something strange, you get up from a couch and look at the door, you see a hand holding a door, and you see his face, its hard to see because of dark inside the door, it slowly opens, it reveals to be a man wearing business suit, black tie, black gloves, white skin, grinning face, but you blink your eyes and he disappeared, what will you do?
