Famous quotes containing the word small:
“Rome, like Washington, is small enough, quiet enough, for strong personal intimacies; Rome, like Washington, has its democratic court and its entourage of diplomatic circle; Rome, like Washington, gives you plenty of time and plenty of sunlight. In New York we have annihilated both.”
—M. E. W. Sherwood (1826–1903)
