Ghost of Christmas Past, the Continuing Saga

The Ghost of Christmas Past girl called again yesterday AND today. She is continually asking the same questions about the Polar Express in her child voice. Shannon and I are getting super creeped out. I'm trying to figure out if she's a real person or if she's pranking us or something. I don't know a good way to ask "Are you really a child, or are you an adult with a developmental disability?"
