Famous quotes containing the words double and/or check:
“...the shiny-cheeked merchant bankers from London with eighties striped blue ties and white collars and double-barreled names and double chins and double-breasted suits, who said “ears” when they meant “yes” and “hice” when they meant “house” and “school” when they meant “Eton”...”
—John le Carré (b. 1931)
“The habit some writers indulge in of perpetual quotation is one it behoves lovers of good literature to protest against, for it is an insidious habit which in the end must cloud the stream of thought, or at least check spontaneity. If it be true that le style c’est l’homme, what is likely to happen if l’homme is for ever eking out his own personality with that of some other individual?”
—Dame Ethel Smyth (1858–1944)
