Heart touching story:

A 24 year old boy seeing out from the train's
window shouted:
"Dad, look the trees are going behind!"
Dad smiled and a young couple sitting nearby,
looked at the 24 year old's childish behavior
with pity, suddenly he again exclaimed:
"Dad, look the clouds are running with us!"
The couple couldn't resist and said to the old
man:
"Why don't you take your son to a good
doctor?"
The old man smiled and said:
"I did and we are just coming from the
hospital, my son was blind from birth, he just
got his eyes  today.
