Once upon a time, a Farmer walked through his field one cold winter morning. At ground the Snake, the Stiff and frozen with the cold. The Farmer know how deadly be the Snake and yet he tried to picked it up and put it in his bosom to warm it back to life.
The Snake soon revived and when it had enough strength, unfortunately bit the man who had been so kind to it. The bite was deadly it makes the Farmer felt that he must die. Though as he drew his last breath and said to those standing around, “Learn from my fate do not take pity on a scoundrel”.
So the moral value of this story is completely based on some who never changes their nature, regardless of how good we behave with them & always stay alert in life and try to maintain the distance from those who are there only thinking about their own benefits.
