Famous quotes containing the word double:
“... the next war will be a war in which people not armies will suffer, and our boasted, hard-earned civilization will do us no good. Cannot the women rise to this great opportunity and work now, and not have the double horror, if another war comes, of losing their loved ones, and knowing that they lifted no finger when they might have worked hard?”
—Eleanor Roosevelt (1884–1962)
