Famous quotes containing the words sharp and/or echo:
“Bunched upside down, they sleep in air.
Their sharp ears, their sharp teeth, their quick sharp faces
Are dull and slow and mild.
All the bright day, as the mother sleeps,
She folds her wings about her sleeping child.”
—Randall Jarrell (1914–1965)
“I’ve noticed that the children of other nations always seem precocious. That’s because the strange manners of their elders have caught our attention most and the children echo those manners enough to seem like their parents.”
—F. Scott Fitzgerald (1896–1940)
