Famous quotes containing the word table:
“A man who can dominate a London dinner table can dominate the world. The future belongs to the dandy. It is the exquisites who are going to rule.”
—Oscar Wilde (1854–1900)
“A child who is not rigorously instructed in the matter of table manners is a child whose future is being dealt with cavalierly. A person who makes an admiral’s hat out of linen napkins is not going to be in wild social demand.”
—Fran Lebowitz (20th century)
