Famous quotes containing the word friend:
“Men always sell strawberries, women, blackberries, your all- knowing Creole friend says. ‘Why?’ you ask. ‘Ah, it has always been that way.’ When you get to know Creoles better, you realize that the phrase ‘It has always been that way’ justifies everything.”
—For the City of New Orleans, U.S. public relief program (1935-1943)
