Famous quotes containing the words dark and/or matter:
“Dark, dark my light, and darker my desire
My soul, like some heat-maddened summer fly,
Keeps buzzing at the sill.”
—Theodore Roethke (1908–1963)
“As siblings we were inextricably bound, even though our connections were loose and frayed.... And each time we met, we discovered to our surprise and dismay how quickly the intensity of childhood feelings reappeared.... No matter how old we got or how often we tried to show another face, reality was filtered through yesterday’s memories.”
—Jane Mersky Leder (20th century)
