Billy knew there were monsters that lived under his bed and the only thing that protected him was when he was tucked in really tightly at night so the monsters couldn't sneak under the covers. When he tried to explain this to his daddy, he was told to stop being silly. His daddy had taken him by the hand and looked under the bed to show Billy that there was nothing scary under there. Of course there wasn't, that was because the monsters were made of shadows and only came out when it was dark. When Billy's daddy put him to bed that night, he didn't tuck him in tightly enough and the monsters crept under the covers and they ate him.
