Famous quotes containing the word friend:
“Twenty-two weeks the men were out as the strike moved into winter. It was strange to go out into the street and find the men there in the daytime. It had a feeling of fright in it. And always the mood of the men grew uglier as empty bellies and desperation began to conquer reason. Any man who was not their friend became their enemy. They knew my father had opposed the strike, and now it was they who opposed him.”
—Philip Dunne (1908–1992)
