Sandpaper is a strange thing.. Can we make it a metaphor for anything.. many things evil and many things good come to my mind.. but it is a queer necessary evil.. It can roughen any patch we want and the same thing can smoothen any patch we want.. Same difference.. like its bent on making the two sides of the coin same.. or making these two words the two sides of the coin? It looks glittery but it can peel of the glitter of you.. thats one way of thinking, the negative, pessimistic view of things.. but it looks so rough but it can softly take away the undulations where you want it to vanish… much like a running stream smoothens all the stones it comes by and makes them into beautiful pebbles. Beauty is in the eyes of the beholder and faces deceive..
