    There is probably not one person, however great his virtue, who cannot be led by the complexities of life’s circumstances to a familiarity with the vices he condemns the most vehemently—without his completely recognizing this vice which, disguised as certain events, touches him and wounds him: strange words, an inexplicable attitude, on a given night, of the person whom he otherwise has so many reasons to love.
    Marcel Proust (1871–1922)

    People are lucky and unlucky not according to what they get absolutely, but according to the ratio between what they get and what they have been led to expect.
