Small child #1: But I don't want to be a cop! I want to be a robber!
Small child #2: Too bad, you have to be a cop.
Small child #1: Why can't we all just be robbers, then we can steal stuff and no one can catch us?
Small child #2: Because, stupid… that's how it is! Robbers and cops! It's no fun to be a robber if there aren't any cops to chase you! –Outside Brooklyn Church
