Graveyard

One man went to the grave to visit his mothers tomb. He kept the flowers he had taken there and placed it on his mothers grave and prayed for some time. Then while he was returning, he heard a very loud cry from his left. He turned towards that direction and walked there.
He saw a man crying nearby a tomb. He was crying very aloud and uttering the words "Why did you die? Why did you die?" and crying with deep sorrow.
Seeing the man crying so hard, he asked him "Sir, why are you crying so much. Is the person your wife, father, mother, friend or any other close relative of yours?" The man crying told that he was his wife's first husband.
