—Jeremy Taylor (1613–1667)
“The heart is forever inexperienced.”
—Henry David Thoreau (1817–1862)
“[He] didn’t dare to, because his father had a weak heart and habitually threatened to drop dead if anybody hurt his feelings. You may have noticed that people with weak hearts are the tyrants of English married life.”
