One day a old man was going to take part in a religious ceremony.
At the same time a young man was going to meet his fiancé.
On the way, both of them started talking and they both became good friends of each other.
The young man said, Dear Sir,
I wish you come with me to meet my fiance..

But the old man refused and said,
No thanks, I am going to a religious function.
That's why I wanted you to come with me too..
The young man politely refused and Then both of them went on their own way..
When that gentleman went to the religious ceremony, he started thinking about the beautiful lady whom he had got the chance to meet..
On the other side, the young man started thinking about that religious ceremony. where he had the opportunity to go..
Thus both were thinking about that which they did not get.
The nature of a person is such that by not thinking about what he already has, He keeps thinking about the things available to others..........!!
