So the real question isn't "What would you do if you could freeze time?"
Would you be kind? A benevolent poltergeist who fixes broken things? Would you be cruel? A thief who steals a single second from every happy memory? Or would you be lonely ? Someone who just wanted to stand in front of another frozen person, look them in the eye, and whisper, "I was here. I existed. See me."
Go ahead. Stop the clock. But remember: every frozen world eventually melts. And when it does—they will come looking for the one who walked between the seconds.
You become a ghost in their timeline. A teaser trailer for a story they didn't know they were in.
