Famous quotes containing the words drinking and/or bird:

—Denise Levertov (b. 1923)
“They tell us sometimes that if we had only kept quiet, all these desirable things would have come about of themselves. I am reminded of the Greek clown who, having seen an archer bring down a flying bird, remarked, sagely: “You might have saved your arrow, for the bird would anyway have been killed by the fall.””
—Elizabeth Cady Stanton (1815–1902)
