Fairytale about pessimist and optimist

Whilome optimist and pessimist met each other. Pessimist said to optimist: «Optimist, the world around you is full of vivid colors, you always see only the good in everything. But the world around me is gray and ugly, and it does not have anything cheerful, and I am horribly unhappy from it. Tell me, why am I only dragging out an existence, and you live a full life?»
«I do not know, — optimist answered him. — I am amazed at why people sometimes do not see joy and happiness where I see them. I would like to understand why some people are sad all the time, although the world around them is so beauteous».
Optimist and pessimist were silent for a moment. Then optimist quoth: «Pessimist, why do not we exchange our eyes for the day and look at the world otherwise: you will see the world just like I see it, and I will see the world just like you see it. I will know why some people are unhappy, and you will know what it means to be happy».
«Well, — pessimist said — I agree».
And optimist and pessimist exchanged their eyes, agreed to meet at the same place at the same hour and went about their business.
Optimist was totally struck by the scene. The world around him lost all its colors and became faded and dim. Thick dark clouds were in the sky and there was a strong rainstorm. Many people were running about their business, pushing optimist, clamping him in the crowd and were fighting very much in this case. Initially, it was very scary and upsetting him. Optimist barely got out of the crowd, was soaking wet, hid under a little roof and started to wait when the rain stopped because he had no umbrella. However, later optimist looked closer and noticed that even if the rainstorm was strong, it was fair. Raindrops were drumming on the roof rhythmically and with a pleasant knock, a lot of rivulets with pleasant murmurs were running on the cracked asphalt like blood through the slim veins. Colorful umbrellas were presented with a crowd and violating all gray picture around that admired optimist. Over some time the rainstorm ended and optimist gasped from suddenly arising beauty. All around — asphalt, glass windows, tree leaves — were glimmering in the drops of water like in the diamonds, and luminous signs and street lights were reflecting in big puddles. Optimist had a lot of fun. He saw all the magnificence around with joyful amazement, cheerfully leaped over puddles and rivulets and breathed deeply air which was extremely fresh after a rainstorm. So far the whole day optimist walked even, at first glance, with gloomy sky overhead.
And pessimist was totally fascinated by the scene. The world around him became vivid and light. Joyful and happy people were going around, the sun was shining on the ideally clear sun and the air was very warm. Initially, pessimist very like it, he was going on the streets with joy, admiring beauty around, smiling every passer-by because first time in a while he was so much better in the soul. But the pleasure was not long. Shortly pessimist understood that the sun was baking him, stuffiness was reigning around, and he himself got bored enormously, and he felt creepy tiredness. He started to find a place that he can relax but nothing pleased him: it had too much sun or was too close or children played on the playground nearby from whose screams he was having a ringing in his ears. Again all began to irritate pessimist, calmly passing and smiling people had become hateful to him, he did not want to see anybody. Finally, he found an oak in the depth of one public garden, hid under it and remained so far all the rest of the day, stifling heat and wishing that it was all to end soon.
A day later optimist and pessimist met at the same place at the same hour. Pessimist lashed out at optimist:
«You deceived me! — he screamed — The world around me had been light and colorful but the same ugly as always! People with their smiles had irritated me, in the streets it had been unbearably warm, and it had not been possible to spend time doing something useful! Life is so unfair to me, how could you have done this cruelly to me?»
«I did not deceive you, — optimist said to him. — I do not understand what the deal is. The world through your eyes had been gray and dim, many angry people had gone around and it had been awful raining. But even so, the streets of the city had been madly fair, I had not angered for tired people passing by, breathed deeply and felt happy. I am so sorry that it happened».
«You can take your eyes and send my eyes to me! I abhor you!» — pessimist screamed and threw the eyes of optimist on the land so much that they were shattered. After this pessimist took his eyes away optimist and left.
Pessimist came back to his home, continued to live his life. However, resentment towards optimist did not subside in his soul. He was angry at him, he was angry that his eyes had been useless and had not helped to become happy. From this his life became even more gray and even more ugly.
Once pessimist went on the street and met a little boy who sat on the bench and cried. Pessimist approached him and asked: «What are you doing here, and why are you crying?».  «The car, — boy answered in tears. — I have lost my car which I was playing with. I can not find it anywhere».
After hearing this answer pessimist hit a boy. «And you are sobbing due to this silly? — pessimist screamed at boy — Do you even know how much this world disgusts me? I look at the people every day and see only malformed faces, and only coldness, tightness and darkness around me. Therefore, I should cry, not you!»
Boy cried even more and shouted in response: «Mister, you are bad! You will never see beauteous world, you will never become happy!» — and boy ran away. To which pessimist shouted after him: «We will see about that!»
Then pessimist started to wander the Earth, to meet people, to request for their eyes so that he might see a list of drops of happiness. However, nobody was not giving their eyes and all people were running away terrified because they were seeing how much lousy, lousy wight stood before them. Eventually pessimist did not find the eyes which he could see happiness with in the world and remained left-left alone.
And blind optimist first had been wandering the land alone too. He was crying very much because he had no more eyes which he saw on the vivid and colorful world around, and it was very-very painful for him. For the first time optimist knew a true woe.
But once optimist went into the park and heard something strong crying. He followed the noise, and as soon as the crying faded, like the holder of this crying saw an unknown person, optimist asked: «Who are you, and why are you crying so much?». «The ball. I was playing with a ball and lost it. I have checked all the bushes, but I can not find any».
The voice full of sorrow belonged to a little girl. Then optimist told: «Do not cry, I will help you find it».
And optimist began to seek the ball, and horribly he struggled to do this because he does not have eyes, and he can rely only on hands, but a lot of minutes of searching later, finally optimist sensed a circle and smooth toy in his hand. Excited about this, optimist came to the girl again and gave ball her.
«My ball! — girl shouted, stopped to cry and picked up cherished toy. But there she asked: «Mister, why are your eyes covered?».
Optimist was silent. Girl took his hand and told: «Let us go with me, I will lead you. You do not see anything, you can get lost».
And optimist with girl went so, and she was holding the hand of him. And after they did not separate, they became true friends. After this optimist met still many people, and all they were glad to him because they were seeing how much he is worthye person. Let he had eyes in order to see all colors of this world, but their colors always were in his soul.
After all, optimist lived his life happily, being blind, and pessimist lived his life unhappily, being sighted.
Maybe that was not eyes still?
