Shaftmonde. Sorry I don't remember that particular story, but this might make you smile, although it didn't make me smile at the time.
I was about 14yrs old, and one dark winter night my mum and dad had gone to the cinema, and my younger brother and sister were in bed.
I was listening on the radio in the kitchen to The Man in Black telling a very scary story which took place in a dentist's surgery. Now we had a piano in the sitting room, and just at the most scary point of the story, came the tinkle, tinkle, tinkle on the piano keys. I quickly shut the door to the adjoining room, and sat shivering and scared to death until my mum and dad got home. Only for Dad to discover that our kitten had managed to get itself shut in the sitting room, and was happily parading up and down the piano keys. I hope you enjoyed that little tale, and I hope you find the answer to your question. Best wishes. Schutz.
