My grandma told me a story
Once a father and his 3 sons lives in a village. One day the father met with a terrible accident , so death comes to take the father. Oldest son begs to the death to let his father live for some years, death was kind and so agreed.
After an year and half death returned back to take away the father with him.Second son beg and so death agreed and grant him some more time.
After 6 months death returned again to take the father.
Now the youngest son request to allow his father to live till the candle wick of the candle on his hand burned out.Death agreed.
Now as the youngest son thought , the death never returned back.
How come ?
