Famous quotes containing the words shared, secret and/or keys:
“The danger lies in forgetting what we had. The flow between generations becomes a trickle, grandchildren tape-recording grandparents’ memories on special occasions perhaps—no casual storytelling jogged by daily life, there being no shared daily life what with migrations, exiles, diasporas, rendings, the search for work. Or there is a shared daily life riddled with holes of silence.”
—Adrienne Rich (b. 1929)
“The secret of biography resides in finding the link between talent and achievement. A biography seems irrelevant if it doesn’t discover the overlap between what the individual did and the life that made this possible. Without discovering that, you have shapeless happenings and gossip.”
—Leon Edel (b. 1907)
“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)
