    ““What care I for a goose-feather bed,

    Along with the wraggle taggle gipsies, O!””

    “In the game of love, the losers are more celebrated than the winners.”
    —Mason Cooley (b. 1927)

    “Surely the fates are forever kind, though Nature’s laws are more immutable than any despot’s, yet to man’s daily life they rarely seem rigid, but permit him to relax with license in summer weather. He is not harshly reminded of the things he may not do.”
    —Henry David Thoreau (1817–1862)
