Famous quotes containing the word plans:
“One who winks the eyes plans perverse things; one who compresses the lips brings evil to pass.”
—Bible: Hebrew, Proverbs 16:30.
“A father ... knows exactly what those boys at the mall have in their depraved little minds because he once owned such a depraved little mind himself. In fact, if he thinks enough about the plans that he used to have for young girls, the father not only will support his wife in keeping their daughter home but he might even run over to the mall and have a few of those boys arrested.”
—Bill Cosby (20th century)
“The important thing about travel in foreign lands is that it breaks the speech habits and makes you blab less, and breaks the habitual space-feeling because of different village plans and different landscapes. It is less important that there are different mores, for you counteract these with your own reaction- formations.”
—Paul Goodman (1911–1972)
