Famous quotes containing the words common and/or designs:
“The line of separation was very distinct, and the Indian immediately remarked, “I guess you and I go there,—I guess there’s room for my canoe there.” This was his common expression instead of saying “we.” He never addressed us by our names, though curious to know how they were spelled and what they meant, while we called him Polis. He had already guessed very accurately at our ages, and said that he was forty-eight.”
—Henry David Thoreau (1817–1862)
“I have nothing against the Queen of England. Even in my heart I never resented her for not being Jackie Kennedy. She is, to my mind, a very gallant lady, victimized by whoever it is who designs the tops of her uniforms.”
—Leonard Cohen (b. 1934)
