The other day, Johanna gave Sam his first "piano lesson."
She showed him middle C; how to hold his hands - rounded, not flat; and how to play the first song in her old piano book.
Ever since then, Sam has had intense practice sessions of 10 or 15 minutes, playing that SAME piece over and over and over.
On the plus side, maybe this means he's ready to start piano lessons in earnest this fall.
Look out, Liberace!
