Famous quotes containing the word ideal:
“The Ideal Man should talk to us as if we were goddesses, and treat us as if we were children. He should refuse all our serious requests, and gratify every one of our whims. He should encourage us to have caprices, and forbid us to have missions. He should always say much more than he means, and always mean much more than he says.”
—Oscar Wilde (1854–1900)
