Prompt: Write a short story about a man who discovers a magical portal

Timothy was out for a walk one day when he stumbled upon a strange portal. He stepped through and found himself in a strange land. He saw a beautiful city with towering buildings and a bright sky. He walked around and saw people of all races and ages living freely. He felt a sense of joy and happiness in this new place and decided to stay for a while. Timothy found work and started to make a new life for himself. He was happy to be able to live in peace and harmony with all the people here. One day, though, he discovered that the portal had disappeared. He was sad to have to leave this wondrous place, but knew that he had to go back to the real world. Timothy always remembers the time he spent in this magical land and hopes that he can return one day.
