" 'Ah,' Anselmo took the cup, put his head back and let [the whiskey] run down his throat. He looked at Maria standing holding the bottle and winked at her, tears coming down from both eyes. 'That,' he said. 'That.' Then he licked his lips. 'That is what kills the worm that haunts us.'"
- Ernest Hemingway, "For Whom the Bell Tolls"
(emphasis added by me). I could go ahead and analyze that quote, but I don't think any more words are necessary in defense of a man who drinks. Hemingway nailed it.
