Apparently I cursed myself

so according to my sculpture teacher i am being cursed by a stone.... i spent the afternoon sawing through this amazingly beautiful piece of alabastor... ya apparently your never supposed to saw such a nice piece in two.... he says i've brough an artists curse to myself... that the stone won't work out for me... hog wash, first peice that broke off broke perfectly into the shape of what i was carving.... thus proving that curses and superstitions are crap
