When you are old and grey and full of sleep,
And nodding by the fire, take down this book,
And slowly read, and dream of the soft look
Your eyes had once, and of their shadows deep
— W. B. Yeats,, from “When You are Old,” The Collected Poems of W. B. Yeats. (Scribner; 2nd Revised edition September 9, 1996) Originally published 1889.
