Famous quotes containing the word essential:
“A slight digression: that bit about my mother was a deliberate lie. In reality, she was a woman of the people, simple and coarse, sordidly dressed in a kind of blouse hanging loose at the waist. I could, of course, have crossed it out, but I purposely leave it there as a sample of one of my essential traits: my light-hearted, inspired lying.”
—Vladimir Nabokov (1899–1977)
