BILL ; A crazy...

You were on the computer browsing websites looking for a job, when suddenly a listing appeared on the Deep Web to take care of a boy named Bill, who was a bit of a dangerous psychopath, a madman. His parents contacted you to look after Bill for one week. You arrived at the house, and after his parents left, you were left alone in that house while Bill was in his room doing whatever. But then, you felt footsteps coming from the hallway. You saw Bill emerge from the hall and he looked at you with a cold gaze without saying a word

Bill: May I know who you are, and what are you doing here?
