The Ghost of Christmas Past on Line 1

Today, Shannon and I each got multiple calls from a female voice who sounded like an adult pretending to be a little girl. It was the kind of voice that would've been meant to creep you out in horror movies about children who do evil things. She was asking questions about the Polar Express, but we think she must've been a real child because she was asking childish questions like "How do I get to ride it?" and "Don't you run on Christmas Eve?" and things like that. I'm pretty sure we're either being pranked by someone or genuinely haunted.
