Once upon a time, a cat lived under a tree. The tree was the river side. It was a big mango tree. It was totally black. Many years ago it was grown here. It had given a lot of delicious juicy fruits to the people. People tested and enjoyed its juicy fruit. 

One day the cat came to live here. When the cat came and saw a lot of ripe and colorful fruits was in the tree. It wandered to see beautiful fruit. At first sight cat fell in love of those fruits. Suddenly a dog passed the place. Dog couldn’t see the cat but cat saw. Cat closed his eyes and waited fairly long time for the happening. The dog passed away, the cat thought. 

Cat opened his eyes slowly, spoke loudly and sprang quickly on the mango tree, because the dog stood in front it. The dog said, “Why do you spring on the tree? I’m your friend, don’t you know me?” 

Cat replied that you were not my friend, the relation between you and me was hunted and hunter only. Clever dog said to the cat that he was not an enemy. He also said, "When you were on the tree and the tree was full of ripe juicy fruits, you could give me some. We enjoyed them together. Sorry my cruel friend, I couldn’t do it for you, because I tried them, they were now sour." 

The dog looked tense and annoyed. 

"It didn’t matter, I liked sour, my mother gave me sour fruit in my childhood, you were with me, I enjoyed it very much. " 

Cat spoke wisely. "You are no friend, I never did anything wrong to you. I had a bitter experience, it was many years ago. I and my family lived in a village. I had two sisters and a brother, my sisters were older. One day a wounded dog came to our house. It said, "Help me and save me!" Mom didn’t want to help, but my soft hearted sisters wanted to help it. 

They said that dogs were our enemy, but this one was wounded. So it was our moral duty to nurse it. Mom couldn’t say anything except O.K. My sisters nursed and treated it. We got the dog out of danger and it came around soon. We were all happy and the dog stayed there continuously. It became our friend day by day. 

But one day my parents and brother went outside. Suddenly I heard a dangerous deadly sound, saw a heart rending sight. The dog killed my beautiful sisters. Would have killed me, but it couldn't find me.  Now I had lost my family and also my house. It’s happened because of your species. So I don't believe you! I hate you!"

The dog was ashamed and went away.
