I was down stairs alone watching the Simpsons at like 10:00, the door was locked thankfully and I heard a guy singing, and I thought, "someone's tryin' to be Micheal Jackson over here", but it was kind of weird. My sister came down a minute later and she asked me if I heard the teenager boy singing outside by the front door, and she said it was really weird because she opened the door to the balcony and no one was there, she said it really freaked her out. I think my house is haunted.
