One cold morning in winter, I went alone to a hillside to do some hunting. I sat there waiting for about an hour. Suddenly, a big beautiful deer appeared less than 20 feet away from me. There was no cover near him. Surely I could shoot him.
To my surprise, he came toward me! He was curious, I suppose, or maybe he was stupid. For this was not a youngster, but a fully grown-up one. He must have known about men and their guns. But this deer came closer, and I still waited. His big eyes never moved away from my face. His wonderful head with a set of antlers (鹿角) was clear in sight.
I was getting a bit nervous as he walked closer. A big deer can do a lot of damage. Well, he walked right up to where I was sitting. Then he stopped and looked at me.
What happened next was hard to believe. But it all seemed quite natural. I held out my hands and scratched his head right between the antlers. And he liked it. The big, wild, beautiful deer bent his head.
I scratched and touched his head and body. His nose touched my shoulder. I fed him with my last sandwich.
Well, he finally went his way, down the hill. Shoot him? Not me. You wouldn’t, either. Not after that. I just watched him go, a strong deer carrying a proud head.
I picked up my gun, and started walking back. Suddenly, I heard two shots, one after another. If you have hunted much, you will know what two shots mean. They mean a kill. I had forgotten that there were other hunters around.
You will now understand why I gave up hunting from that day on.
