Famous quotes containing the words open, game and/or license:

    All the unhurried day
    Your mind lay open like a drawer of knives.
    Philip Larkin (1922–1985)

    I have a notion that gamblers are as happy as most people, being always excited; women, wine, fame, the table, even ambition, sate now & then, but every turn of the card & cast of the dice keeps the gambler alive—besides one can game ten times longer than one can do any thing else.
    George Gordon Noel Byron (1788–1824)

    Surely the fates are forever kind, though Nature’s laws are more immutable than any despot’s, yet to man’s daily life they rarely seem rigid, but permit him to relax with license in summer weather. He is not harshly reminded of the things he may not do.
    Henry David Thoreau (1817–1862)
