'The ring of truth'
‘For people never say anything the same way twice; no two of them ever say it the same. The greatest imaginative writer that ever brooded in a lavender robe and a mellowed briar in his teeth, couldn't tell you, though he try for a lifetime, how the simplest strap-hanger will ask the conductor to be let off at the next stop...
It is all for the taking. All the manuals by frustrated fictioneers on how to write can't give you the first syllable of reality, at any cost, that any common conversation can. All the classics, read and re-read, can't help you catch the ring of truth as does the word heard first-hand.'
Nelson Algren, author of The Man with the Golden Arm and A Walk on the Wild Side.
