One day, a dog has a
nice piece of meat for his dinner. He goes home happily with the meat in his
mouth. On his way home, there is a river. The water is still (平静的)and clear. He stops to take a look at it.
What does he see? There is a dog as big as himself and he has some meat in his
mouth, too. "I'll try to get it. And I'll have a big dinner today.
"He opens his mouth to get it. But just then his own meat falls into the river.
He goes home sadly. What does the dog have for dinner today?
