It's wrong to make threats.
Sam lives with his father Bill, who notices that his son's room is a mess.
Bill wants Sam's room to be cleaned.
Bill kindly asks Sam if he'll clean his room and tempts him with a treat as a reward.
Bill threatens to spank Sam if he doesn't clean his room immediately.
Sam cleans his room immediately and it looks spotless.
Sam is defiant and runs away to his friend's house in response to the threat.
