He said in a high voice, “See Dad, the green trees and the scenery are very beautiful!” It made the other people feel very strange. Everyone started talking in a low voice about the old man’s son. Suddenly, it started raining. Raindrops fell on the travelers through the open window. Seeing the rain, the old man’s son said happily, “See Dad, how beautiful the rain is!” Hearing these words, a young lady became angry with the man, as the raindrops were dropping on her new clothes. She couldn’t help shouting at the noisy son and his father.

“Can’t you see it is raining? You! Old man! If your son is not feeling well, get him to a mental hospital quickly and please don’t disturb us any more!” The old man’s face turned slightly red and then in a low voice, he replied, “We are on the way back from hospital. He was blind at birth. Only last week he can see again. The rain and the nature are new to him. Please forgive him.” All the other people became quiet.
