Because I didn't move that extra piece of the stirrup leather that had scrunched up between my knee and the saddle. You know that extra piece of which I speak. Not during tempis. Not during collected-medium-collected transitions. Not even during canter pirouettes. I was just too lazy to move it. And now I have a sore.
Procrastination has paid off again. Oh yes, procrastination has paid off again.
