Mistakes. More often than not, they sit on the surface of the page, staring up at you, yet this is only temporarily uncomfortable. Within a few simple strokes of an eraser on its black lettering, we can remove the existence of the mistake leaving behind the soft, rubber piling that the eraser made on the page. But some mistakes scratch deeper, and when they do the eraser is useless. Oh, you can rub all you like, but the smudge gets dirtier, bigger, frightening in its persistence.
