In the hospital in one room were two seriously ill people.

In the hospital in one room were two seriously ill people. One lay by the window, and the other's bed was located at the door. 

"What do you see outside the window?" - asked the one lying near the door. 
"Outside the window", the first one replied: "I see the sky, clouds resembling little animals, a lake and a forest in the distance."

Every day, at the window, he told his neighbor about what was happening outside the window. He saw a boat, fishermen with a huge catch, children playing on the beach, young lovers holding hands. 

While he was watching all these amazing events outside the window, his neighbor was tormented by a deadly malice. "It's not fair," he thought. "What kind of merits did he get looking out the window, and not me, and I can only see the door with peeling paint, while he admires the view from the window?" 

Once lying at the window, he coughed heavily and began to choke. He tried to reach the nurse's call button, but he did not have the strength, because he shuddered with a cough. Neighbor watched what was happening. He could have pressed the button, but he did not.
After a while, the first calmed down and stretched out on his bed. 
When he was carried away, the neighbor asked the nurse to be moved to the window. 

The nurse complied with the request of the patient, went over to his bed, helped him to lie on the opposite bed and, making sure that the patient was comfortable, then went towards the door. Suddenly she was stopped by the astonished exclamation of the patient: 

"How so! This window overlooks a blank gray wall! But the one who died told me that he saw a forest, a lake, clouds, people ... How could he see all this from this window?" 

The nurse smiled sadly. 

"He could not see anything at all; your deceased neighbor was blind."
