A Walk on the Wild Side is a 1956 novel by Nelson Algren, also adapted into the 1962 film of the same name. Set in Depression era, it is "the tragi-comedy of Dove Linkhorn", a naive Texan drifting from his hometown to New Orleans. Algren noted, "The book asks why lost people sometimes develop into greater human beings than those who have never been lost in their whole lives. Why men who have suffered at the hands of other men are the natural believers in humanity, while those whose part has been simply to acquire, to take all and give nothing, are the most contemptuous of mankind." It is most often quoted for Algren's "three rules of life": "Never play cards with a man called Doc. Never eat at a place called Mom's. Never sleep with a woman whose troubles are worse than your own." Source: Wikipedia (en)
