Yesterday I was sent a short clip of my dad playing the harmonica. It was terrible. He was enjoying himself immensely. As you know, he is/was an artist and after his stroke a few years ago, his hand was incapable of the same precision.
If you could see the difference between before and after, a child has taken his place. He paints most days still. I am not sure if it is because he has come to accept the limitation, or his mind does not realise.
