A hungry fox was wandering in the forest. Then she saw bunches of grapes hanging from a vine. They looked ripe and juicy.
The fox jumped but the grapes were too high. She tried again and still could not reach them. After many jumps and failures, she sat down exhausted.
She looked around to see whether anyone had seen her. Then, making a face, she said, “Those grapes are sour anyway. Who would eat them!” and walked away.
