One day, a Mother Crab and her baby were walking together. The Baby Crab was walking a little ahead of the Mother.
After a while, the Mother Crab said, “Why do you bend towards one side when you walk, my child?”
The Baby Crab turned back and looked at its Mother and asked, “Why Mother, what is wrong with the way I walk?”
The Mother Crab replied, “It does not look good.
You look much better when you walk straight and forward.” The young Crab said, “This might be quite true, Mother. But I do not know how to walk straight. So, if you will show me how to walk straight, I will promise to do so, too.”
His Mother readily agreed and said, “Look carefully now
When the Mother tried to walk straight, it was impossible for her also to walk that way.
She kept trying, but she could not walk straight. Tired, she said to her son, “I am sorry for scolding you. I myself cannot walk in a straight manner. How can I ask you to do so?” She then told her son, “You continue to walk the way you do!”
Example is more powerful than speech.
