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

Greg was baffled when he found the odd, green portal in his back yard. He had no idea how it got there, but there it was, seemingly out of nowhere. After a few hesitant moments, Greg finally decided to go through it.

He found himself in a strange, green world filled with strange creatures. He didn’t know what to do, but he knew he had to find his way back home. He walked for hours, but eventually he realized he was lost. Just as he was about to give up, he saw the portal shimmering in the distance. He ran towards it, but as he got closer, he realized it was fading. Just before it disappeared completely, he saw a figure standing behind it. It was a woman with long, brown hair. She smiled at him and said goodbye.

Greg never found out what happened to the woman, but he always remembered her smile and the feeling of belonging he felt when he saw her. He knew he would never forget the portal, and he would always be grateful for the chance to visit her world.
