Frustration stiffens my fingers, making the task I have set for myself infinitely more difficult as my fingers wander across the piano keys, trying to find something pleasing. My urgency, too, makes the frustration more poignant. I know Dmitri will be ending his lessons soon and then he will come to fetch me for luncheon, after which we will go back to my posing for his painting. His challenge for me to play for him has been burning in the back of my mind since he issued it, but even more so in these past few afternoons of standing in a river as he paints and not even being allowed a glimpse at the progress.
