Famous quotes containing the words grey and/or gold:
“Indeed, my mother’s beautiful face still shone with youthfulness that night when she so softly held my hands and sought to stop my tears; but, precisely, it seemed to me that this should not have happened, her anger would have saddened me less than this new sweetness that my childhood had never known; it seemed to me that, with a hidden and impious hand, I had just traced the first wrinkle and made appear the first grey hair in her soul.”
—Marcel Proust (1871–1922)
“Arrive in the afternoon, the late light slanting
In diluted gold bars across the boulevard brag
Of proud, seamed faces with mercy and murder hinting
here, there, interrupting, all deep and debonair,
The pink paint on the innocence of fear;
Walk in a gingerly manner up the hall.”
—Gwendolyn Brooks (b. 1917)
