Carolyn's children saw a ghost the other night. They were out in the garden trying to photograph foxes. Their friend was with them, so they took her photograph:
When they saw the result, they thought they'd photographed a ghost. It startled the crap out of them. They ran screaming into the house and begged their mum to lock all the doors.
Silly children! Don't you know that ghosts can walk through doors?
(Only joking: there's no such thing as ghosts really!)
