Famous quotes containing the word table:
“The newspaper is a Bible which we read every morning and every afternoon, standing and sitting, riding and walking. It is a Bible which every man carries in his pocket, which lies on every table and counter, and which the mail, and thousands of missionaries, are continually dispersing. It is, in short, the only book which America has printed, and which America reads. So wide is its influence.”
—Henry David Thoreau (1817–1862)
“The best thing about Sassy Seats is that grandmothers cannot figure out how they work and are in constant fear of the child’s falling. This often makes them forget to comment on other aspects of the child’s development, like why he is not yet talking or is still wearing diapers. Some grandmothers will spend an entire meal peering beneath the table and saying, “Is that thing steady?” rather than, “Have you had a doctor look at that left hand?””
—Anna Quindlen (20th century)
“Language was vigorous because, because ... editors usually “laid all the cards on the table so as to leave their hands ... free for more persuasive arguments!” The citizenry at large retaliated as best they could.”
—State of Utah, U.S. public relief program (1935-1943)
