Famous quotes containing the words moment and/or area:
“How truly does this journal contain my real and undisguised thoughts—I always write it according to the humour I am in, and if a stranger was to think it worth reading, how capricious—insolent & whimsical I must appear!—one moment flighty and half mad,—the next sad and melancholy. No matter! Its truth and simplicity are its sole recommendations.”
—Frances Burney (1752–1840)
“Many women are reluctant to allow men to enter their domain. They don’t want men to acquire skills in what has traditionally been their area of competence and one of their main sources of self-esteem. So while they complain about the male’s unwillingness to share in domestic duties, they continually push the male out when he moves too confidently into what has previously been their exclusive world.”
—Bettina Arndt (20th century)
