One day the wind found a lost letter. The rain had washed away the words on the envelope and so no one could understand who had written it and for whom.

The letter contained two wonderful words: "I love you." The wind lifted the letter high, higher and higher, and carried it away. The letter, all alone, would find its destination and make someone feel loved. But the wind could never imagine that this letter would land on the head of Mr. Cat, who was always grumpy and lived locked up in his house.

Always? Who knows, perhaps these two wonderful words could change his life.
