Am just finishing sniffling and sobbing over the thought of that poor piano being banished...I was lucky enough to have piano lessons and followed the exams/festivals/ route but was always more tempted by picking out the latest pop song or tv theme or just 'going off on one' tinkling and plonking along. I am glad I had that background because I feel I have the best of both worlds now I have moved onto playing in bands and such, (well ok, I had to buy a stage piano cos my childhood one has to stay at home!)
Glad you are enjoying the guitar etc but don't be too hard on the old piano...for me it is a wonderful instrument, so versatile and so beautiful, funny, powerful, poignant...I could go on for ever raving about it (And I probably am raving, too!)
If I didn't have my piano, or keyboards, accordion etc...I would definitely have to take up smoking, hardened drinking, some form of mind-altering substance as I would lose one of the greatest fixes of my life. Long live the piano cos I will always love you.
