Famous quotes containing the words exit and/or list:
“Exit the mental moonlight, exit lex,
Rex and principium, exit the whole
Shebang. Exeunt omnes. Here was prose
More exquisite than any tumbling verse:
A still new continent in which to dwell.”
—Wallace Stevens (1879–1955)
“Lovers, forget your love,
And list to the love of these,
She a window flower,
And he a winter breeze.”
—Robert Frost (1874–1963)
