I went to the fruit stand to buy fruit. I noticed only a child, about ten years old, was minding the shop. So I asked, "Little brother, which of these two pears is better?" "The one on the right!" the child pointed without hesitation. Just then, the owner returned, greeted me, and I casually asked again, "Sir, which kind of pear should I buy?" "The one on the left, of course!" the owner pointed without thinking. I laughed, "But the little brother just told me the one on the right is better!" He suddenly slapped the child: "This is your uncle, a good friend, you have to tell the truth!"
