Famous quotes containing the words year and/or galactic:

    In another year I’ll have enough money saved. Then I’m gonna go back to my hometown in Oregon and I’m gonna build a house for my mother and myself. And join the country club and take up golf. And I’ll meet the proper man with the proper position. And I’ll make a proper wife who can run a proper home and raise proper children. And I’ll be happy, because when you’re proper, you’re safe.
    Daniel Taradash (b. 1913)

    In sci-fi convention, life-forms that hadn’t developed space travel were mere prehistory—horse-shoe crabs of the cosmic scene—and something of the humiliation of being stuck on a provincial planet in a galactic backwater has stayed with me ever since.
    Barbara Ehrenreich (b. 1941)
