Famous quotes containing the words dark and/or matter:
“—the dark ajar, the rocks breaking with light,
and undisturbed, unbreathing flame,
colorless, sparkless, freely fed on straw,
and, lulled within, a family with pets,
—and looked and looked our infant sight away.”
—Elizabeth Bishop (1911–1979)
“The people who resent me do so because I’m a woman, I’m young, and I’m a Bhutto. Well, the simple answer is, it doesn’t matter that I’m a woman, it doesn’t matter that I’m young, and it’s a matter of pride that I’m a Bhutto.”
—Benazir Bhutto (b. 1953)
