Because she really loves playing the flute.
She'd lost her music stand and book a bit ago, so I hadn't heard her practicing at home as much. Just that medley. But I replaced the book and stand this week, and just... nonstop. Whenever she's not watching TV (which she only gets an hour of per weekend-day), eating, or reading, she is playing that flute.
And she's really good.
And really excited about music.
