Oh why did you have to leave me?

A man is visiting the cemetery to place flowers on the grave of his dearly departed mother.  He places the flowers on the grave and is walking back towards his car when he notices another man kneeling at a grave.  The man seemed to be praying with profound intensity and repeating, “Why did you have to die?  Why did you have to die?”

The first man was touched and decided to approach him.  “Sir, I don’t wish to interfere with your private grief, but this demonstration of pain is more than I’ve ever encountered before.  For whom do you mourn so deeply?  A child?  A parent?”

The mourner took a moment to collect himself and then replied, “My wife’s first husband.”
