In just one paragraph from Book 1, Chapter 5 of A Tale of Two Cities, Charles Dickens teaches a master-class to those of us who would use similes to make communication more vivid.
The faintness of the voice was pitiable and dreadful. It was not the faintness of physical weakness, though confinement and hard fare no doubt had their part in it. Its deplorable peculiarity was, that it was the faintness of solitude and disuse. It was like the last feeble echo of a sound made long and long ago. So entirely had it lost the life and resonance of the human voice, that it affected the senses like a once beautiful colour faded away into a poor weak stain. So sunken and suppressed it was, that it was like a voice underground. So expressive it was, of a hopeless and lost creature, that a famished traveller, wearied out by lonely wandering in a wilderness, would have remembered home and friends in such a tone before lying down to die.
