Famous quotes containing the words smart and/or materials:
“Often, we expect too much [from a nanny]. We want someone like ourselves—bright, witty, responsible, loving, imaginative, patient, well-mannered, and cheerful. Also, we want her to be smart, but not so smart that she’s going to get bored in two months and leave us to go to medical school.”
—Louise Lague (20th century)
“Though the hen should sit all day, she could lay only one egg, and, besides, would not have picked up materials for another.”
—Henry David Thoreau (1817–1862)
