Famous quotes containing the words ancient and/or times:
“It is worth the expense of youthful days and costly hours, if you learn only some words of an ancient language, which are raised out of the trivialness of the street, to be perpetual suggestions and provocations. It is not in vain that the farmer remembers and repeats the few Latin words which he has heard.”
—Henry David Thoreau (1817–1862)
“Why does a man take it for granted that a girl who flirts with him wants him to kiss her—when, nine times out of ten, she only wants him to want to kiss her?”
—Helen Rowland (1875–1950)
