Famous quotes containing the word reading:
“There are women in middle life, whose days are crowded with practical duties, physical strain, and moral responsibility ... they fail to see that some use of the mind, in solid reading or in study, would refresh them by its contrast with carking cares, and would prepare interest and pleasure for their later years. Such women often sink into depression, as their cares fall away from them, and many even become insane. They are mentally starved to death.”
—Ellen Henrietta Swallow Richards (1842–1911)
“I knew you forever and you were always old,
soft white lady of my heart. Surely you would scold
me for sitting up late, reading your letters....”
—Anne Sexton (1928–1974)
