Famous quotes containing the word puzzle:

    What are you now? If we could touch one another,
    if these our separate entities could come to grips,
    clenched like a Chinese puzzle . . . yesterday
    I stood in a crowded street that was live with people,
    and no one spoke a word, and the morning shone.
    Everyone silent, moving. . . . Take my hand. Speak to me.
    Muriel Rukeyser (1913–1980)
