Famous quotes containing the word table:
“They were not on the table with their elbows.
They were not sleeping in the shelves of bunks.
I saw no men there and no bones of men there.”
—Robert Frost (1874–1963)
“The one happiness is to shut one’s door upon a little room, with a table before one, and to create; to create life in that isolation from life.”
—Eleonora Duse (1859–1924)
“In New York, pretending to be above the struggle means no seat on the bus and a table next to the kitchen.”
—Mason Cooley (b. 1927)
