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

    It is open to a war resister to judge between the combatants and wish success to the one who has justice on his side. By so judging he is more likely to bring peace between the two than by remaining a mere spectator.
    Mohandas K. Gandhi (1869–1948)

    Life is a game in which the rules are constantly changing; nothing spoils a game more than those who take it seriously. Adultery? Phooey! You should never subjugate yourself to another nor seek the subjugation of someone else to yourself. If you follow that Crispian principle you will be able to say “Phooey,” too, instead of reaching for your gun when you fancy yourself betrayed.
    Quentin Crisp (b. 1908)

    Only one marriage I regret. I remember after I got that marriage license I went across from the license bureau to a bar for a drink. The bartender said, “What will you have, sir?” And I said, “A glass of hemlock.”
    Ernest Hemingway (1899–1961)
