A Crab said to her son, "Why do you walk so one-sided, my child?
It is far more becoming to go straight forward." The young Crab
replied: "Quite true, dear Mother; and if you will show me the
straight way, I will promise to walk in it." The Mother tried in vain,
and submitted without remonstrance to the reproof of her child.
Example is more powerful than precept.
