The old man and his joyful 25 year old son

An old man was sitting with his 25 year old son in a train. As the train was leaving the station, the young man was filled with joy and curiosity. As he was sitting by the window, he waved his hand outside in the open air. He shouted, "Papa see all trees are going behind". The old man smiled and admired his son's feelings.
Beside the young man was a couple that were sitting and listening to the whole conversation between the father and the son. They felt a little awkward with the attitude of the young, good-looking man who was behaving like a small child. The handsome man then shouted, "Papa see the pond and animals. The clouds are moving with the train".

The couple can see the young man was now embarrassed. It started raining and some of the water drops touched the man's hand. He was filled with joy and he closed his eyes. He shouted again," Papa it's raining, I can see the water droplets on my palm, see papa". The couple couldn't help themselves and asked the old man. “Why don't you visit the Doctor and get a treatment for your son?” The old man said," We are from the hospital. Please excuse my son, he had just got his eyes for the first time in his life. He's been blind since he was born".

Moral: "Do not draw any conclusions before you know all the facts and reasons"
