An 80-year-old man was sitting on the sofa in his house along with his 45-year-old highly educated son. Suddenly a crow(乌鸦) rested on their window. The father asked his son, “What is this?” The son replied “It is a crow.” After a few seconds the father asked his son the second time, “What is this?” The son said, “Father, I just now told you; it is a crow.” After a little while, the old man again asked his son the third time, “What is this?” At this time some expression of anger was felt in the son’s tone when he said to his father, “It is a crow, a crow.” A little later, the father again asked his son the fourth time, “What is it?” This time the son shouted at his father, “Why do you keep asking me the same question again and again? Although I have told you so many times? It is a crow. Are you not able to understand this?” A little later the father went to his room and came back with an old diary which he had kept since his son was born. On opening a page, he asked his  son to read that page. The following words were written in it: Today my little son aged three was sitting with me on the sofa. When a crow was sitting on the window, my son asked me 23 times what it was, and   I replied to him all 23 times that it was a crow. I hugged him lovingly each time he asked me the same question again and again for 23 times. I did not at all feel angered. I rather felt affection for my innocent(单纯的) child.
