An Old Crab said to her son, “Why do you walk sideways like that, my son? You ought to walk straight.” The Young Crab replied, “Show me how, dear mother, and Ill follow your example.” The Old Crab tried, but tried in vain, and then saw how foolish she had been to find fault with her child.
Moral of the story:
Example is better than precept.
We will teach others more effectively by being a good example than we will by telling them what to do.
