Famous quotes containing the word spot:
“If a person lost would conclude that after all he is not lost, he is not beside himself, but standing in his own old shoes on the very spot where he is, and that for the time being he will live there; but the places that have known him, they are lost,—how much anxiety and danger would vanish.”
—Henry David Thoreau (1817–1862)
