By the way, my relationship with pianos that are not my own remind me strongly of reactions dogs have to other dogs. :)
"It's a dog! I'm a dog! Dog! Dog!"
I literally cannot control myself when I see a #piano somewhere. I want to touch it, want to play it and hear its sound. It's like there's a invisible magnet that always drags me towards a piano. :)
Too bad in most places with unexpected pianos they are just for decoration, probably not even serviced. And they won't let you touch them :(
