Famous quotes containing the words time, curtain and/or travel:

    A great proportion of architectural ornaments are literally hollow, and a September gale would strip them off, like borrowed plumes, without injury to the substantials.... What if an equal ado were made about the ornaments of style in literature, and the architects of our bibles spent as much time about their cornices as the architects of our churches do? So are made the belles-lettres and the beaux-arts and their professors.
    Henry David Thoreau (1817–1862)

    Old politicians, like old actors, revive in the limelight. The vacancy which afflicts them in private momentarily lifts when, once more, they feel the eyes of an audience upon them. Their old passion for holding the centre of the stage guides their uncertain footsteps to where the footlights shine, and summons up a wintry smile when the curtain rises.
    Malcolm Muggeridge (1903–1990)

    Good news about someone never gets past the door, but bad news will travel a thousand leagues away.
    Chinese proverb.
