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

I was sitting outside of my apartment, scrolling through my phone when I saw a notification from my landlord. Apparently, one of the elevators had been out of service for a while and they were going to need to move some of my things up to the fourth floor. I told myself not to get my hopes up, but I decided to go check the elevator just in case.

To my surprise, I found a hidden door that led to a hidden passageway. The passageway led to a magical portal that took me to another world. I explored the world for a while, but eventually I returned to my apartment and forgot all about the portal.
