小王子是法国作家圣埃克苏佩里的名著《小王子》中的主人公。他在旅途中遇到了一朵非常特别的玫瑰花。在他离开玫瑰花后，他经常思念她，并回忆起他们之间的对话。以下是其中的一些经典句子的英文对话：

One classic line from the conversation between the little prince and his rose is:

"Goodbye," said the fox. "And now here is my secret, a very simple secret: It is only with the heart that one can see rightly; what is essential is invisible to the eye."

Another memorable quote from the book is:

"Men have forgotten this truth," said the fox. "But you must not forget it. You become responsible, forever, for what you have tamed."

The little prince replied, "What is essential is invisible to the eye," and the fox agreed, saying, "It is the time you have wasted for your rose that makes your rose so important."

These lines from the conversation between the little prince and his rose are some of the most famous in the book. They speak to the importance of love, connection, and responsibility, and remind us that the things we value most in life are often the things that are not immediately visible to us.
