—Bernice Weissbourd (20th century)

“In proportion as our inward life fails, we go more constantly and desperately to the post office. You may depend on it, that the poor fellow who walks away with the greatest *number* of letters, proud of his extensive correspondence, has not heard from himself this long while.”

—Henry David Thoreau (1817–1862)

“At thirty years a woman asks her lover to give her back the esteem she has forfeited for his sake; she lives only for him, her thoughts are full of his future, he must have a great career, she bids him make it glorious; she can obey, entreat, command, humble herself, or rise in pride; times without *number* she brings comfort when a young girl can only make moan.”

—Honoré De Balzac (1799–1850)
