Penny has an ear for music

Why does Penny rush out of the house whenever I play the piano? For most of her life I haven't touched the piano, but I do remember that when she was a puppy I occasionally played a few times - badly, I'll freely admit - and she behaved as if she hated the sound.

It hasn't changed. I've decided it might be good for my ageing brain and my levels of stress if I played  the piano regularly. Last August I started on a few old favourite pieces, but it was disheartening to hear the immediate tick-tack of the doggy door as she left the house, so I stopped.

And once again...

What's it all about? I'm not that bad, surely. At least she doesn't jump up and try to stop me, like this dog does.

At last I've stopped playing and I'm on this computer, so she can have a little sleep, tucked up with one of her favourite balls.
