当然可以。以下是一个经典的伊索寓言故事，名为《狐狸和葡萄》（The Fox and the Grapes）：
The Fox and the Grapes
Once upon a time, there was a fox who saw a cluster of ripe grapes hanging from a high vine in a garden. The fox was very hungry and wanted to eat the grapes. He tried to jump up to reach them, but he was not able to get them.
The fox tried and tried again, jumping higher and higher, but still, the grapes were just out of reach. Finally, after many attempts, the fox gave up and walked away, looking very disappointed.
A nearby crow saw this and asked the fox why he was so sad.
“I am sad,” replied the fox, “because I am hungry and I wanted to eat those grapes. But I couldn’t reach them, no matter how hard I tried.”
The crow, feeling sorry for the fox, said, “But why are you so sad? The grapes were probably sour and not worth eating anyway.”
The fox thought about this for a moment and then smiled. “Oh, well, that’s what I thought all along. I was just too proud to admit it.”
And so, the fox left the garden with a smile on his face, feeling better about himself because he had realized that the grapes were not worth the effort after all.
这个寓言故事告诉我们，有时候我们因为得不到某些东西而感到悲伤，可能只是因为我们自己认为那些东西不值得拥有。
