Once upon a time, a mighty Lion was caught in a hunter's net. A tiny Mouse, who had previously bothered the Lion, came to its aid. The resourceful Mouse, remembering the lion's kindness of sparing the tiny creature's life, gnawed through the ropes that bound the Lion, setting it free. The Lion, initially amused by the idea of a Mouse helping him, learned that even small acts of kindness have their rewards.
The fable teaches that no being is too small to help another and kindness is never wasted.
