Famous quotes containing the words instant and/or presence:
““Heaven nor hell shall impede my designs,” said Manfred, advancing again to seize the princess. At that instant the portrait of his grandfather ... uttered a deep sigh and heaved its breast. ... Manfred ... saw it quit its panel, and descend on the floor with a grave and melancholy air.”
—Horace Walpole (1717–1797)
“The presence of a grandparent confirms that parents were, indeed, little once, too, and that people who are little can grow to be big, can become parents, and one day even have grandchildren of their own. So often we think of grandparents as belonging to the past; but in this important way, grandparents, for young children, belong to the future.”
—Fred Rogers (20th century)
