" Friendship is a sacred word, a holy thing; it is never developed except between persons of character, and never takes root except through mutual respect; it flourishes not so much by kindnesses as by sincerity. What makes one friend sure of another is the knowledge of his integrity: as guarantees he has his friend's fine nature, his honor, and his constancy. "

― Étienne de La Boétie , The Politics of Obedience: The Discourse of Voluntary Servitude
