It is said that an old man was sitting on the train with his 25-year-old son. Much of the joy and curiosity was evident in the features of the young man who was sitting by the window. He took his hands out of the window and felt the passage of air. "Dad, I see all these trees walking behind us!" The old man smiles, in agreement with his son's joy. Next to them was a couple listening to what was going on between the father and his son. They felt a little embarrassed, how a young man behaves like this child! Suddenly the young man shouted again: "Father, look at the pond and its animals, look at the clouds how to go with the train." The couple continued to wonder about the young man's conversation again. Then the rain began, and the drops of water fell on the young man's hand, whose face was filled with happiness, and cried again: "My father is raining, and the water touched my hand, see, Dad." "Why do not you visit the doctor and get treatment for your son?" Said the old man. "We are coming from the hospital, because my son has become a first-time sighter!" Always remember: "Do not draw conclusions until you know all the facts."
