A fool doing some stupid thing a second time is like a dog going back to its vomit. Sensible people will see trouble coming and avoid it, but an unthinking person will walk right into it and regret it later. There is more hope for a stupid fool than for someone who speaks without thinking. But if you correct a wise man, he will respect you. Stupid people always think they are right.
Wise people listen to advice.
If you don't punish your son, you don't love him. If you do love him, you will correct him. Wisdom is a fountain of life to the wise, but trying to educate stupid people is a waste of time. A warning given by an experienced person to someone willing to listen is more valuable than gold rings or jewellery made of the finest gold. Even if you beat a fool until he's half dead, you still can't beat his foolishness out of him.
