The Babysitter

(This is a true story) A man called a babysitter and told her to go upstairs and look in on the children. She ignored the man so he called again and again. She finally got fed up and asked the operator to trace the man's call. When the operator traced it, it made the babysitter's skin crawl. The operator told her to get out of the house because the calls were coming from upstairs. The man had already killed the children and he was going to kill her when she came up there.
