The Little Princess doesn’t like her light to be turned off at bedtime because she’s scared of ghosts. Everyone tells her that they don’t exist. She finally agrees that any ghosts would be very small, and probably afraid of the dark. Once her light is turned off a little ghost does appear, but is just as scared of the Little Princess as she is of him. The Little Princess scares him away by saying ‘Boo!’ The ghost runs back to his mother, who tells him that little girls don’t exist, but he asks to keep his light on, just in case.
