Famous quotes containing the words shared, secret and/or keys:
“When young people are too rigidly sequestered from [the world], their lively and romantic imaginations paint it to them as a paradise of which they have been beguiled; but when they are shown it properly, and in due time, they see it such as it really is, equally shared by pain and pleasure, hope and disappointment.”
—Frances Burney (1752–1840)
“To the man who cherishes a secret in his breast, there is a still greater secret unexplored. Our most indifferent acts may be a matter for secrecy, but whatever we do with the utmost truthfulness and integrity, by virtue of its pureness, must be transparent as light.”
—Henry David Thoreau (1817–1862)
“Bless all useful objects,
the spoons made of bone,
the mattress I cook my dreams upon,
the typewriter that is my church
with an altar of keys always waiting.”
—Anne Sexton (1928–1974)
