You know when someone asks: "Wow, who taught this kid to be so polite?" When you obey, say "thank you," and don't fight, Mom and Dad's hearts fill up with joy! It's like you're giving us an invisible gift.
But if you make a mess out in public, people think: "Wow, his dad didn't teach him anything." The Bible says the wise child is the father's pride. When you get it right, you're defending Dad!
