One quiet morning, I found an old key hidden in a wooden box. It looked ordinary, but it seemed to carry a secret. I followed a tiny mark engraved on it to a forgotten door. When I turned the key, the lock clicked open with a soft sound. Inside was a small room filled with letters from my past. Each letter reminded me of dreams I had once forgotten. I smiled and realised the key had not opened a roomโit had opened my heart. From that day on, I carried the key as a reminder that every ending can unlock a new beginning.
