Famous quotes containing the words signed and/or group:
“You watched and you saw what happened and in the accumulation of episodes you saw the pattern: Daddy ruled the roost, called the shots, made the money, made the decisions, so you signed up on his side, and fifteen years later when the women’s movement came along with its incendiary manifestos telling you to avoid marriage and motherhood, it was as if somebody put a match to a pile of dry kindling.”
—Anne Taylor Fleming (20th century)
“Once it was a boat, quite wooden
and with no business, no salt water under it
and in need of some paint. It was no more
than a group of boards. But you hoisted her, rigged her.
She’s been elected.”
—Anne Sexton (1928–1974)
