我相信他是随迁徙的候鸟离开的。临走那天早晨，他好好地整理了他的星球。他仔细将活火山打扫干净。他有两座活火山。它们用来加热早餐很方便。他还有座死火山。但就像他说的：“以后的事谁知道呢！”所以他也清扫了死火山。如果打扫干净，火山就会慢慢地、稳定地燃烧，不会突然喷发。火山喷发和烟囱着火差不多。显然，在地球上，我们显得太小了，没法清理火山。所以它们带来了许多麻烦。
I believe that for his escape he took advantage of the migration of a flock of wild birds. On the morning of his departure he put his planet in perfect order. He carefully cleaned out his active volcanoes. He possessed two active volcanoes; and they were very convenient for heating his breakfast in the morning. He also had one volcano that was extinct. But, as he said, "One never knows!" So he cleaned out the extinct volcano, too. If they are well cleaned out, volcanoes burn slowly and steadily, without any eruptions. Volcanic eruptions are like fires in a chimney.

On our earth we are obviously much too small to clean out our volcanoes. That is why they bring no end of trouble upon us.

小王子还有点伤感地拔除了最后几株猴面包树的幼苗。他觉得自己是不会回来的。但这些熟悉的劳动在那个早晨显得特别温馨。他给花浇了最后一次水，准备把她放到玻璃罩里，这时他发现自己很想哭。
The little prince also pulled up, with a certain sense of dejection, the last little shoots of the baobabs. He believed that he would never want to return. But on this last morning all these familiar tasks seemed very precious to him. And when he watered the flower for the last time, and prepared to place her under the shelter of her glass globe, he realised that he was very close to tears.

“再见，”他对花儿说。
但她没有回答。
“再见，”他又说。
花儿咳嗽了。但这不是因为她着了凉。
"Goodbye," he said to the flower.
But she made no answer.
"Goodbye," he said again.
The flower coughed. But it was not because she had a cold.

“我以前很笨，”她终于开口了，“对不起。祝你幸福。”
"I have been silly," she said to him, at last. "I ask your forgiveness. Try to be happy…"

他很惊讶花儿居然没有责怪他。他愣住了，玻璃罩也停在半空。他无法理解这种平静的甜蜜。
He was surprised by this absence of reproaches. He stood there all bewildered, the glass globe held arrested in mid-air. He did not understand this quiet sweetness.

可是会有风的啊……”
"But the wind--"

“我的感冒没那么严重……夜里凉爽的空气对我有好处。我可是花耶。”
"My cold is not so bad as all that… the cool night air will do me good. I am a flower."

“可是会有昆虫和野兽的……”
"But the animals--"

“我愿意忍受两三条毛毛虫的，因为我想认识蝴蝶。听说蝴蝶很漂亮。否则谁来探望我呢？你就要去远方啦。至于大动物，我可不怕，我有爪子的。”
"Well, I must endure the presence of two or three caterpillars if I wish to become acquainted with the butterflies. It seems that they are very beautiful. And if not the butterflies-- and the caterpillars-- who will call upon me? You will be far away… as for the large animals-- I am not at all afraid of any of them. I have my claws."

“别磨蹭了，这让我很难受的。既然你决定要离开，那就走吧。”
"Don't linger like this. You have decided to go away. Now go!"

因为她不希望让小王子看到她流泪。这朵花还真是骄傲啊……
For she did not want him to see her crying. She was such a proud flower…
