Famous quotes containing the words double and/or check:
“American families, however, without exception, experience a double message in our society, one that claims a commitment to families and stresses the importance of raising bright, stable, productive citizens, yet remains so bound by an ideal of “rugged individualism” that parents receive little support in their task from the public or private sectors.”
—Bernice Weissbourd (20th century)
“Is there no hope for me? Is there no way
That I may sight and check that speeding bark
Which out of sight and sound is passing, passing?”
—Paul Laurence Dunbar (1872–1906)
