Studying, Huh?

Two of my piano students, Caroline W and Emma, come together for lessons. While one is at the piano, the other is playing "Staff Wars" (a computer game to teach note recognition) on my computer.

At least, that's what I thought Caroline was doing.

One week later I open up photo booth to record a section of my Chopin Etude, and I find this!

What is this?!

Sorry, Caro, but if you leave them on my computer, you'd better just assume they're blog material.

Oh, and you have a sight-reading test this afternoon. ;)
