大寶： Why did Mommy yell at you?
小寶： Because I didn't finish my bread.
大寶： Your bread? Isn't that your breakfast?
大寶： If that is your breakfast, why does she yell at you now?
小寶： What do you mean?
大寶： If Mommy is angry at you because you didn't finish your breakfast, she should have been yelling at you in the morning, not in the evening! She didn't yell at you in the morning, but yelled at you just now, that doesn't make any sense!!! Does it?
小寶： So, you mean, she is supposed to yell at me in the morning if she is really angry at me because I didn't finish my breakfast in the morning. She yelled at me in the evening. That means she is angry about other things?
大寶： That's right! You are a smart boy!
