"An elderly man sat on the train with his 25-year-old son.
As soon as the train started moving, the boy who was sitting by the window was full of excitement.
He put his hand out the window and shouted, “Dad, look, the trees are moving.”
The old man admired his son's excitement with a smile.
In the row in front of them, there was a young couple who were listening to the words of father and son and were surprised by the movements of the young boy who behaved like a 5-year-old child.
Suddenly, the boy shouted excitedly again: “Dad, look at the lake, the birds and the clouds are moving by train.”
The young couple looked at the boy sometimes with sympathy and sometimes with ridicule.
It started to rain and a few drops fell on the young man's hand.
He touched it with pleasure and shouted again, “Dad, look at the raindrops, they are everywhere.”
The young couple couldn't bear it anymore and asked the old man: “Why don't you go to the doctor for your son's treatment?”
"We are just coming back from the hospital, today my son will be able to see for the first time in his life," said the old man.
