Second Fingers Sorted

Looking at a new piece with an 8-yr-old.

Me: What's the key signature?
Girl: C..No, F sharp.
Me: So, wh-
Girl: Do is G.
Me: Good... How are you going to do the first note?  High two or low?
Girl: Um... [thinks a bit]... High!
Me: Why? [this often makes them change their mind, regardless of whether or not they're correct]
Girl: Because it's a mi.
Me [delightfully surprised]: Yes!  How about on the D string?
Girl [slight thinking pause]: High.  Because it's a ti.
Me: A string?
Girl [takes a little while, I think she's thinking up the G major scale from the open G]: Low.  Because it's a fa, and fa is best friends with mi.

Yay!
