Famous quotes containing the words list of, list, minimum and/or curve:

    My list of things I never pictured myself saying when I pictured myself as a parent has grown over the years.
    Polly Berrien Berends (20th century)

    We saw the machinery where murderers are now executed. Seven have been executed. The plan is better than the old one. It is quietly done. Only a few, at the most about thirty or forty, can witness [an execution]. It excites nobody outside of the list permitted to attend. I think the time for capital punishment has passed. I would abolish it. But while it lasts this is the best mode.
    Rutherford Birchard Hayes (1822–1893)

    After decades of unappreciated drudgery, American women just don’t do housework any more—that is, beyond the minimum that is required in order to clear a path from the bedroom to the front door so they can get off to work in the mourning.
    Barbara Ehrenreich (20th century)

    The years-heired feature that can
    In curve and voice and eye
    Despise the human span
    Of durance—that is I;
    The eternal thing in man,
    That heeds no call to die.
    Thomas Hardy (1840–1928)
