Here's an interesting story:
Once there was a boy called Peter. He was a strong, able boy, but he did not enjoy going to school and he was forever daydreaming.
"Peter, what are you dreaming about this time?" his teacher would say to him.
"I'm thinking about what I'll be when I grow up," Peter replied.
"Be patient. There's plenty of time for that. Being grown up isn't all fun, you know," his teacher said.
But Peter found it hard to enjoy whatever he was doing at the moment. In winter he longed for it to be summer again, and in summer he looked forward to the skating, sledging, and warm fires of winter. At school he would long for the day to be over so that he could go home, and on Sunday nights he would sigh, "If only the holidays would come."
Often he would wander through the forest, day-dreaming of the future. Sometimes he would lay down on the soft forest floor in the warm sun, his hands behind his head, staring up at the sky through the distant treetops. One hot afternoon as he began to grow sleepy, he heard someone calling his name. He opened his eyes and sat up. Standing before him was an old woman, and in her hand she held a silver ball, from which dangled a silken golden thread.
"See what I have got here, Peter," she said, offering the ball to him.
"What is it?" he asked curiously, touching the fine golden thread.
"This is your life thread," the old woman replied. "Do not touch it and time will pass normally. But if you wish time to pass more quickly, you have only to pull the thread a little way and an hour will pass like a second. But I warn you, once the thread has been pulled out, it cannot be pushed back in again.
Peter took the gift from her joyfully. It was just what he wanted. He put the ball in his pocket and ran home.
The following day at school, Peter sat day-dreaming about what he would do with his magic thread. The teacher scolded him for not concentrating. If only, he thought, it was time to go home. Then he felt the silver ball in his pocket. Very carefully he took hold of it and tugged. Suddenly the teacher was telling everyone to pack up their books and to leave the classroom for the day. Peter was overjoyed. He ran all the way home. How easy life would be now! All his troubles were over. From that day forth he began to pull the thread, just a little, every day.
One day, however, it occurred to him that it was stupid to pull the thread just a little each day. If he gave it a harder tug, school would be over altogether. Then he could start learning a trade. So that night he gave the thread a hard tug, and in the morning he awoke to find himself apprenticed to a carpenter in town. He loved his new life, clambering about on roofs and scaffolding, lifting and hammering great beams into place that still smelled of the forest. But sometimes, when payday seemed too far off, he gave the thread a little tug and suddenly the week was drawing to a close and it was Friday night and he had money in his pocket.
Peter began to grow impatient for the day when they would be married. He took the magic ball, and for a moment he hesitated; then his impatience got the better of him, and he tugged at the golden thread. In the morning he awoke to find that the year was over and their beside him was his young wife. Now Peter felt truly happy.
A few months later Peter's wife announced that she was going to have a child. Peter was overjoyed and could hardly wait. When the child was born, he felt that he could never want for anything again. But whenever the child was ill or cried through the sleepless night, he gave the thread a little tug, just so that the baby might be well and happy again.
Times were hard, and so Peter gave the golden thread another tug. Years flex by and he 'discovered' that he had yet more children.
As the number of his children grew, so his house became more overcrowded. He would have to extend it, but for that he needed money. He had other worries too. His mother was looking older and more tired every day. It was of no use to pull the magic thread because that would only hasten her approaching death. All too soon she died, and as Peter stood at her graveside, he wondered how it was that life passed so quickly, even without pulling the magic thread.
One night as he lay in bed, kept awake by his worries, he thought how much easier life would be if all his children were grown up and launched upon their careers in life. He gave the thread a mighty tug, and the following day he awoke to find that his children had all left home for jobs in different parts of the country, and that he and his wife were alone.
His hair was almost white now and often his back and limbs ached as he climbed the ladder or lifted a heavy beam into place. His wife, too, was getting older and she was often ill. He couldn't bear to see her suffer, so that more and more he resorted to pulling at the magic thread. But as soon as one trouble was solved, another seemed to grow in its place. Perhaps life would be easier if he retired, Peter thought. Then he would no longer have to clamber about on drafty, half-completed buildings and he could look after wife when she was ill. The trouble was that he didn't have enough money to live on. He picked up his magic ball and looked at it. To his dismay he saw that the thread was no longer silver, but gray. He decided to go for a walk in the forest to think things over.
It was a long time since he had been in that part of the forest. The small saplings had all grown into tall fir trees, and it was hard to find the path he had once known. Eventually he came to a bench in a clearing. He sat down to rest and fell into a light doze. He was woken by someone calling his name, "Peter! Peter!" He looked up and saw the old woman he had met so many years ago when she had given him the magic silver ball with its golden thread. She looked just as she had on that day, not a day older. She smiled at him.
"So, Peter, have you had a good life?" she asked.
"I'm not sure," Peter said. "Your magic ball is a wonderful thing. I have never had to suffer or wait for anything in my life. And yet it has all passed so quickly. I feel that I have had no time to appreciate, understand and enjoy what has happened to me, neither the good things nor the bad. Now I feel there is so little time left, and I have regrets. I dare not pull the thread again for it will only bring me to my death. I do not think your gift has brought me peace of mind."
"How ungrateful you are!" the old woman said. "In what way would you have wished things to be different?"
"Perhaps if you had given me a different ball, one where I could have pushed the thread back in as well as pulling it out. Then I could have relived the things that went badly."
The old woman laughed. "You ask a great deal! Do you think that God allows us to live our lives twice over? But I can grant you one final wish."
"What is that?" Peter asked.
"Choose," the old woman said. Peter thought hard.
At length he said, "I should like to live my life again as if for the first time, but without your magic ball. Then I will experience the bad things as well as the good without cutting them short, and at least my life will not pass as swiftly and meaninglessly as a daydream."
She stretched out her hand, and Peter placed the silver ball in it. Then he sat back and closed his eyes with exhaustion. When he awoke he was in his own bed. His youthful mother was bending over him, shaking him gently.
"Wake up, Peter. You will be late for school', his mother said. He looked up at her in surprise and relief.
As Peter walked to school, he noticed what a bright summer morning it was, the kind of morning when it felt good to be alive. Soon he would see his friends and classmates, and even the prospect of lessons didn't seem so bad. In fact he could hardly wait.
