Famous quotes containing the words table and/or residues:
“They were not on the table with their elbows.
They were not sleeping in the shelves of bunks.
I saw no men there and no bones of men there.”
—Robert Frost (1874–1963)
“You were born into a different world that will present you with different gifts and challenges. A new vision of manhood will be called for that does not tie so closely into the more aggressive and competitive residues of our male character. You will need to search out new ways of expressing strength, showing mastery, and exhibiting courage—ways that do not depend upon confronting the world before you as an adversary.”
—Kent Nerburn (20th century)
