Hank has been requesting, and has not yet received, piano instruction. His wish to take lessons has been noted, but cannot be fulfilled until this coming fall. So, for now, he plugs along on his own, staring intently at Madeleine's easier piano books and trying to make some sense of the notes he sees on the page.
That first day he decided to teach himself piano, it didn't take long before he found the notes on the page corresponded to a particular note on the piano, and shortly after that he was plunking out a few simple songs.
I am reminded, once again, that when a person decides they want to learn something we're, by and large, able to do so, often on our own.
