Famous quotes containing the words early, usage and/or term:
“At the earliest ending of winter,
In March, a scrawny cry from outside
Seemed like a sound in his mind.
He knew that he heard it,
A bird’s cry, at daylight or before,
In the early March wind.”
—Wallace Stevens (1879–1955)
“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)
“Why did you give no hint that night
That quickly after the morrow’s dawn,
And calmly, as if indifferent quite,
You would close your term here, up and be gone”
—Thomas Hardy (1840–1928)
