The hero or heroine receives this fortune while in a public restaurant on earth or elsewhere depending on the tale, laughs at it, thinks about something witty her or his mother or father would have said in response. The smile freezes on our hero/heroine's face as he/she realizes the response of the parent just won't come from memory, nor that parents face ... and the story begins.
