Marcos was a curious 10-year-old boy with brown hair and eyes as bright as stars. One day, while playing in the dusty attic of his grandmother's house, he found an old pocket watch that seemed to have been hidden there for centuries.
The watch was golden and had a mysterious symbol engraved on its cover, a sun and a moon intertwined. Fascinated, Marcos opened it and discovered that the hands of the clock moved backward.
That night, as Marcos looked at the watch, he wished to return to the day he lost his favorite toy. Suddenly, he found himself there, a year earlier, in his old room.
Surprised, Marcos retrieved his toy. But upon returning to the present, he noticed that some things had changed: his room was painted a different color and his books were no longer where they used to be.
Confused, he used the watch again, this time to prevent a fight he had with his best friend. But upon returning, he discovered that they no longer knew each other.
Marcos realized that each change in the past affected his present in unexpected ways. He decided to investigate the watch further in his grandmother's library.
In an old book, he found the story of the watch: it had belonged to an alchemist who created it to correct his mistakes, but ended up losing everything he loved.
Determined not to make the same mistakes, Marcos decided to make one last trip in time to fix everything that had changed.
After an exciting and enlightening journey, Marcos managed to restore his present, learning that every moment is valuable and that mistakes are part of the learning process.
He hid the watch back in its place, knowing that its greatest power was not to change the past, but to learn from it to improve the present and the future.
