Ghost mouse Many years ago, when my parents and I lived in Lunahuaná. we had a piano. The piano was very old, it was older than my grandfather. Obviously, anybody played the piano but always my father cleaned the piano. One day while we were eating and talking surprisingly the piano sounded itself. Everybody listened the sound and asked How was it possibly happened?. My grandfather told us that a long time ago a musician died in that room. Eventually, I went to the piano and checked it while I was cleaning suddenly a mouse runaway from the piano. In the end, everybody said the muse pianist was playing a track of Beethoven
