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）perched（栖息）on their window.
The father asked his son, "What
is this?" The son replied, "It is a crow."
After a few minutes, the father asked his
son for the second time, "What is this?" The son said, "Father,

asked his son for the third time, "What is this?"
At this time some expression of irritation（恼怒）was felt in the son's tone when he said

is this?"
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 while later the father went to his
room and came back with an old tattered（发皱的）diary, which he had maintained since
his son was born. On opening a page, he asked his son to read that page.
When the son read it, the following words were written in the diary:
"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. I did not
at all feel irritated but I rather felt affection for my innocent son,
