The Two Trees in the Garden

The story below is a childhood tale. The origin and the writer behind it are both obscure to me. Today, the World Wide Web made it possible to dig in for any quote or saying no matter how old. Nevertheless, my search for it was not successful and I found it too meaningful to be buried in my memories so I decided to plant it somewhere in my blog! 

A man had only 2 trees in his garden; one was green and blooming and the other was dead. However he kept on watering the dead tree with hope that one day he might have his dead tree full of life again.

Then one morning, there was two dead trees in that garden.
