Famous quotes containing the words list of and/or list:

    Modern tourist guides have helped raised tourist expectations. And they have provided the natives—from Kaiser Wilhelm down to the villagers of Chichacestenango—with a detailed and itemized list of what is expected of them and when. These are the up-to- date scripts for actors on the tourists’ stage.
    Daniel J. Boorstin (b. 1914)

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