Famous quotes containing the words clock and/or making:
“The clock runs down
timeless and still.
The days and nights turn hours to years
and water in a gutter marks the circle of another world
hating, resentful, and afraid
stagnant, and green, and full of slimy things.”
—Margaret Abigail Walker (b. 1915)
“We as a nation need to be reeducated about the necessary and sufficient conditions for making human beings human. We need to be reeducated not as parents—but as workers, neighbors, and friends; and as members of the organizations, committees, boards—and, especially, the informal networks that control our social institutions and thereby determine the conditions of life for our families and their children.”
—Urie Bronfenbrenner (b. 1917)
