Gentileza
José Datrino, known as prophet Gentileza (11 April 1917 — 28 May 1996) was a Brazilian urban personality, kind of a preacher, which became known from 1980 by making quirky inscriptions under an overpass in Rio de Janeiro, where he walked in a white robe and long beard. "Gentileza gera gentileza" ("Kindness begets kindness") is his most famous phrase.
