Orthoclase feldspar

Amanda at Ballastexistenz has made a beautiful video based on Dave Spicer's 1998 essay, "A Way of Describing Autism". Since rocks and stones are a longtime interest of mine, I have had Dave's page bookmarked since I first read it. I have a pouch with all of the stones described and with the addition of my personal favorite, orthoclase feldspar. Note the classic salmon color of these two specimens and the near 90 degree cleavage in two directions. It is composed mostly of potassium and aluminum silicate. With average density and a hardness of 6, it can be scratched with a knife. I identify strongly with the one on the left.

Did anyone else, when Charlie Brown went trick-or-treating, think that he was the luckiest kid alive to get all those rocks?
