'When a boy looks at and accidentally hides his father's compass and then lies about it, he is forced to stay home and be babysat while the rest of his family goes to the movies. The babysitter doesn't come because her car breaks down, there is a power outage, and the boy ends up being chased by his own reflection. He then tells the reflection that he'll never lie again, and the reflection disappears. Eventually, the family comes home to check if the boy is okay. He tells them his story about the reflection but they don't believe him. They find the compass under his father's desk; the rats actually stole it. The boy then asks if his family believes it but they are suddenly unable to speak.'   (https://en.wikipedia.org/wiki/Uncovered_(short_story_collection))
