For being a bad student I was banished to the 'calaboose' - a bare cell with whitewashed walls and a bench to sit on. I liked it there, because I took along a sketch pad and drew incessantly I could have stayed there forever drawing without stopping
In life you throw a ball. You hope it will reach a wall and bounce back so you can throw it again. You hope your friends will provide that wall.
I understand how you could see something in the root of a tree, a crack in the wall, in an eroded stone or pebble. But marble? It comes off in blocks and doesn't evoke any image. It does not inspire.
