Mother-crab advice

A crab lived by the water with his family. The mother-crab had many babies. The children used to play by the water all day long. Then in the evening they would return home. The mother-crab always gave her children various advices. How to get better, how to grow up, how to get better - these are the pipes that the mother-crab taught her children. The children also followed the words of the mother crab.
One day the mother-crab said to her son, ‘Listen, let me say one thing- never walk backwards.Never rub your body on a wet stone again. Got it?
The boy said, ‘I understand, mother. But don't show me walking in front of you once, mother, so I will learn to walk in front. '
The crab-mother admired the boy's expression in her heart. And I thought to myself, the boy has become quite intelligent.

Principle: Examples are much more instructive than advice.
