Spaw,You demonstrate what I think I have figgered out -- that many of us sing because we are blessed with hearts that are so big they over-fill and must needs reach out into the large space of our fellow human beings in all dimensions. And that is done at times by singing, and at times by simply speaking, and at times by the listening silence with which you gifted Harold's aunt.
If ever there does come a time when you decide to drop the shell, move back, look around, perhaps review things, look down, or any of the other things folks are said to do when they are figuring out what next to pursue by way of a lifetime -- I hope you will see me putting up a small sign on your behalf somewhere, and realize in some small way how appreciated you are. Maybe brass, or polished cedar, or fine rare stone, simply reading:
