"Bad writing is all flesh, and dirty flesh at that: clogged with a build-up of clutter and crud, knick-knacks and fripperies encrusted on every surface, a kind of gluey scum gathering in the chinks"

     This sentence follows one that explains how good writing is "clean as a bleached bone".  I believe a sentence that is bad does not investigate, analyze or infer but it just observes.  When looking at a person, all you originally see is flesh.  After getting to know who they are and their personality, you see beyond their looks.  Good writing is similar, it must go deeper then just what is on the surface.  Bad writing stuffs the page with wordy, rambling sentences that does not specify or dissect.
