A moment of curiosity
A window left open
The afternoon had grown quiet. Across the street, someone opened a window, and the sound of a piano drifted into the room.
“Curiosity,” she said, “is a window left open. Even on the quietest days, something new finds its way in.”
I turned back to my book. The street was the same, but I was listening differently.
Explain the passage
A little space for possibility.
The open window is a metaphor for curiosity. Even when a familiar place seems to offer nothing new, leaving room for surprise can change how we see it.
