The Problem Bit

15-yr-old girl is a boarder, from Hong Kong.  During the holidays she has lessons with her teacher over there, who usually gives her some new music.

Me: Which piece do you want to play for me first?
Girl: This one.  It's ... um... well, it's mostly okay.
Me: Mostly?
Girl: Well, it's just ... this bit... [pointing to the whole of the second page].
Me [laughing]: That's half the piece.
Girl [indignant]: But it's so high!  And fast!
