An old man was seated in the train with his 25-year-old son. As train started, the young man was filled much joy and curiosity.
He was seated on the window side. He stuck out one hand (feel) the passing air. He shouted, "Papa see all the trees are going behind". The old man smiled and (admire) his son's emotions.
There was a couple were seated beside the young man. They were just sitting and listening to the conversation between the father the son. They (probable) thought it's somewhat awkward, (observe) the 25-year-old man was behaving like a small child.
Suddenly the young man again shouted, "Papa see the pond and animals. Clouds are moving with the train". The couple was watching the young man visibly embarrassed of his (behave).
Now it started raining and some water drops touched the young man's hand. He shouted excitedly again, "Papa it's raining. The water (touch) me, see papa".
The couple couldn't help themselves any longer and asked the old man, "Why don't you visit the doctor and get your son treated?" The old man said, "Yes, we were coming from the hospital. Today only my son got eyesight first time in (he) life."
