Here in the hills were buffaloes (野牛). I had even, in my very young days — when I could not live till I had killed one of each kind of African animal — shot a bull out there. Later on, when I was not so interested to shoot as to watch the wild animals, I had been out to see them again. But twice I had to go back without success.

But one afternoon as I was having tea with some friends outside the house, Denys came flying from Nairobi and went over our heads westwards; a little while after he turned and came back and landed on the farm. I drove down to the plane to bring him back, but he would not get out of his plane.

“The buffaloes are out feeding in the hills,” he said, “come out and have a look at them.”

“I cannot come,” I said. “I have got a tea-party up at the house.”

“But we will go and see them and be back in a quarter of an hour,” he said.

This sounded to me like the suggestions which people make to you in a dream. So I went up with him. It did not take us long to see the buffaloes from the air; we counted them as they peacefully mixed and separated on the open ground closed in by bushes. There was one very old big black bull, and a number of young ones; if a stranger had come near to them they would have heard or smelt him at once, but they were not prepared for something from the air. They heard the noise of our machine and stopped feeding, but they did not seem to be able to look up. In the end they realized that something very strange was about; the old bull first walked out in front of the others. Suddenly he began to go down the valley side and after a moment he broke into a run. The whole group now followed him, rushing hurriedly down into the buses. In a small wood of low trees they stopped and kept close together. Here they believed themselves to be out of sight. We flew up and away. It was like having been taken there by a secret unknown route.

When I came back to my tea-party the teapot on the stone was still so hot that I burned my fingers on it.

阅读下面一段文字：发现了快乐是由精神来决定，人类丈化又进了一步。发现这个道理，和发现是非善恶 取决于公理而不取决于暴力，一样重要。公理发现以后，从此世界上没有可被武力完全屈服的人。发现了精神是一切快乐的根据，从此痛苦失掉它们的可怕，肉体减少了专制。精神的炼金术能使肉体痛苦都变成快乐的资料。于是，烧了房子，有庆贺的人；一半食，一瓢饮，有不改其乐的人；千灾百毒，有谈笑自若的人。所以我们前面说，人生虽不快乐，而仍 能乐观。(钱钟书《论快乐》)请回答：

“一箪食，一瓢饮”而能“不改其乐”指的是谁(2分)
