Famous quotes containing the words shared, secret and/or keys:
“But popular rage,
Hysterica passio dragged this quarry down.
None shared our guilt; nor did we play a part
Upon a painted stage when we devoured his heart.”
—William Butler Yeats (1865–1939)
“The great secret that all old people share is that you really haven’t changed in seventy or eighty years. Your body changes, but you don’t change at all. And that, of course, causes great confusion.”
—Doris Lessing (b. 1919)
“without luggage or defenses,
giving up my car keys and my cash,
keeping only a pack of Salem cigarettes
the way a child holds on to a toy.
I signed myself in where a stranger
puts the inked-in X’s”
—Anne Sexton (1928–1974)
