Famous quotes containing the word friend:
“But I go with my friend to the shore of our little river, and with one stroke of the paddle, I leave the village politics and personalities, yes, and the world of villages and personalities behind, and pass into a delicate realm of sunset and moonlight, too bright almost for spotted man to enter without novitiate and probation.”
—Ralph Waldo Emerson (1803–1882)
