Famous quotes containing the word regret:

    “And now, far removed from the loved habitation,
    The tear of regret will intrusively swell,
    As fancy reverts to my father’s plantation,
    And sighs for the bucket that hung in the well.”
    —Samuel Woodworth (1788–1842)

    “Sensible people get the greater part of their own dying done during their own lifetime. A man at five and thirty should no more regret not having had a happier childhood than he should regret not having been born a prince of the blood.”
    —Samuel Butler (1835–1902)

    “No entertainment is so cheap as reading, nor any pleasure so lasting. She will not want new fashions nor regret the loss of expensive diversions or variety of company if she can be amused with an author in her closet.”
    —Mary Wortley, Lady Montagu (1689–1762)
