Famous quotes containing the words exit and/or list:

    Exit the mental moonlight, exit lex,
    Rex and principium, exit the whole
    Shebang. Exeunt omnes. Here was prose
    More exquisite than any tumbling verse:
    A still new continent in which to dwell.
    Wallace Stevens (1879–1955)

    Lovers, forget your love,
    And list to the love of these,
    She a window flower,
    And he a winter breeze.
    Robert Frost (1874–1963)
