Famous quotes containing the words oil and/or red:
“No skilled hands
caress a strangers flesh with lucid oil before
a word is spoken
no feasting
before a tale is told, before
the stranger tells his name.”

“The silence is death.
It comes each day with its shock
to sit on my shoulder, a white bird,
and peck at the black eyes
and the vibrating red muscle
of my mouth.”
—Anne Sexton (19281974)
