Famous quotes containing the words time and/or stretching:

    “And now in one hour’s time I’ll be out there again. I’ll raise my eyes and look down that corridor four feet wide with ten lonely seconds to justify my whole existence.”
    —Colin Welland (b. 1934)

    “O sleep, O gentle sleep,
    Nature’s soft nurse, how have I frighted thee,
    That thou no more wilt weigh my eyelids down
    And steep my senses in forgetfulness?
    Why rather, sleep, liest thou in smoky cribs,
    Upon uneasy pallets stretching thee,
    And hushed with buzzing night-flies to thy slumber,
    Than in the perfumed chambers of the great,
    Under the canopies of costly state,
    And lulled with sound of sweetest melody?”
    —William Shakespeare (1564–1616)
