I listened to this yesterday as I was weaving and felt like I was cheating on my violin back home - the very last, thickest callous on my index finger has just about fallen off (this has taken years) and I feel very vulnerable now that the tip of my index finger isn't protected. In the meantime, I'm developing other callouses on other parts of my hand b/c of weaving. It's amazing how the body adapts, but sad, too, that something that was such a huge part of my life isn't part of it anymore. Eric has been practicing two hours a day on new instruments and it makes me jealous.
But! I can't have it all. I'm happy with what I have now, tender finger and all.
