Famous quotes containing the words cards, luminous and/or marked:

    The world is a puzzling place today. All these banks sending us credit cards, with our names on them. Well, we didn’t order any credit cards! We don’t spend what we don’t have. So we just cut them in half and throw them out, just as soon as we open them in the mail. Imagine a bank sending credit cards to two ladies over a hundred years old! What are those folks thinking?
    Sarah Louise Delany (b. 1889)

    A quibble is to Shakespeare what luminous vapours are to the traveller: he follows it at all adventures; it is sure to lead him out of his way and sure to engulf him in the mire.
    Samuel Johnson (1709–1784)

    ...black women write differently from white women. This is the most marked difference of all those combinations of black and white, male and female.

    Toni Morrison (b. 1931)
