Famous quotes containing the words setting and/or circles:
“Many working mothers feel guilty about not being at home. And when they are there, they wish it could be perfect.... This pressure to make every minute happy puts working parents in a bind when it comes to setting limits and modifying behavior.”
—Cathy Rindner Tempelsman (20th century)
“Before the birth of the New Woman the country was not an intellectual desert, as she is apt to suppose. There were teachers of the highest grade, and libraries, and countless circles in our towns and villages of scholarly, leisurely folk, who loved books, and music, and Nature, and lived much apart with them. The mad craze for money, which clutches at our souls to-day as la grippe does at our bodies, was hardly known then.”
—Rebecca Harding Davis (1831–1910)
