Famous quotes containing the words shared, secret and/or keys:
“When our kids are young, many of us rush out to buy a cute little baby book to record the meaningful events of our young child’s life...But I’ve often thought there should be a second book, one with room to record the moral milestones of our child’s lives. There might be space to record dates she first shared or showed compassion or befriended a new student or thought of sending Grandma a get-well card or told the truth despite its cost.”
—Fred G. Gosman (20th century)
“It is the public scandal that offends; to sin in secret is no sin at all.”
—Molière [Jean Baptiste Poquelin] (1622–1673)
“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)
