" GHOST"

This story happened to my parents in my very own home. We had just bought a new grand piano which was made in the 1920's. It was made by 3 brothers and we had been told they cared very deeply about this piano. Now back to the story. my parents were sitting in the same room as the piano and watching the T.V. All of a sudden the light on the piano began to flicker. Not wanting anything to happen to the lamp they unplugged it. But, even though they had unplugged it, it continued to flicker for 30 minutes! We figured out that maybe the ghosts of the makers of our piano were haunting their beloved piano. Could this be true? I don't know but I wish I did.
