Famous quotes containing the words significance and/or usage:
“The hysterical find too much significance in things. The depressed find too little.”
—Mason Cooley (b. 1927)
“Girls who put out are tramps. Girls who don’t are ladies. This is, however, a rather archaic usage of the word. Should one of you boys happen upon a girl who doesn’t put out, do not jump to the conclusion that you have found a lady. What you have probably found is a lesbian.”
—Fran Lebowitz (b. 1951)
