Famous quotes containing the words signal, passed and/or danger:
“Perhaps having built a barricade when you’re sixteen provides you with a sort of safety rail. If you’ve once taken part in building one, even inadvertently, doesn’t its usually latent image reappear like a warning signal whenever you’re tempted to join the police, or support any manifestation of Law and Order?”
—Jean Genet (1910–1986)
“A tragic irony of life is that we so often achieve success or financial independence after the chief reason for which we sought it has passed away.”
—Ellen Glasgow (1873–1945)
“However, the danger in [socially unbalanced relationships] is that the subjection of the woman temporarily calms the man’s jealousy but also renders it more demanding. He ends up making his mistress live like those prisoners on whom light is shone day and night in order for them to be better watched. And things always end in tragedy.”
—Marcel Proust (1871–1922)
