" Very often inertia, selfishness, and vanity play the greatest role in our trust in others; inertia when we prefer to trust somebody else, in order not to investigate, be vigilant, or act ourselves; selfishness when the desire to speak about our own affairs tempts us to confide in someone else; vanity when it concers something that we are proud of. "

― Arthur Schopenhauer , Parerga and Paralipomena
