Life has a way of interfering with our practice time. And if it doesn't get done, well, nobody's happy!
ME brought her music to practice last night and the first thing she pulls out is a Poulenc Sonata; it's easy, she says, very slow. It's the second movement.
Hmmm. Not THIS Sunday. How about 3 weeks. (I'm going to be camping for one of those weeks.)
YIKES! It will be fine in 3 weeks.
