"Son,  never trust a man who doesn't drink because he's probably a 
self-righteous sort,  a man who thinks he knows right from wrong all the time. Some of 
them are good  men, but in the name of goodness, they cause most of the 
suffering in the world.  They're the judges, the meddlers. And, son, never trust a 
man who drinks but  refuses to get drunk. They're usually afraid of something 
deep down inside,  either that they're a coward or a fool or mean and violent. 
You can't trust a  man who's afraid of himself. But sometimes, son, you can 
trust a man who  occasionally kneels before a toilet. The chances are that he is 
learning  something about humility and his natural human foolishness, about 
how to survive  himself. It's damned hard for a man to take himself too 
seriously when he's  heaving his guts into a dirty toilet bowl."
