Famous quotes containing the word table:
““A sigh for every so many breath,
And for every so many sigh a death.
That’s what I always tell my wife
Is the multiplication table of life.””
—Robert Frost (1874–1963)
“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)
“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)
