Exact Cover Problem

    The first moments of sleep are an image of death; a hazy torpor grips our thoughts and it becomes impossible for us to determine the exact instant when the “I,” under another form, continues the task of existence.

    You may call a jay a bird. Well, so he is, in a measure—because he’s got feathers on him, and don’t belong to no church, perhaps; but otherwise he is just as much a human as you be. And I’ll tell you for why. A jay’s gifts and instincts, and feelings, and interests, cover the whole ground. A jay hasn’t got any more principle than a Congressman.
    Mark Twain [Samuel Langhorne Clemens] (1835–1910)

    The problem with marriage is that it ends every night after making love, and it must be rebuilt every morning before breakfast.
    —Gabriel García Márquez (b. 1928)
