After she came back from the market, Zeng Zi told her to kill a pig for their meal.
She said, “I did not mean it!”
Zeng Zi replied, “How could you? Do not ever think that children don’t understand! Whatever parents do, they will imitate. If we lied to him, aren’t we telling him that it’s OK to lie?”
So, Zeng Zi went and killed his pig and let his son have pork.
