The fool treats wrongdoing as entertainment — a moral failure that reveals deep disorder. The person of understanding has wisdom as their 'sport' — their delight.
Memory phrase: Wise people delight in wisdom, not mischief.
Talk about it: Why do you think some people find trouble-making fun? What can be even more fun that is also good?
Prayer: God, help me find delight in wisdom and good things — not in causing trouble or mischief.
