I don't think life offers any greater experience than the joyful sense of recognition when one finds in a new acquaintance a real friend, or when an old relationship deepens into friendship, or when one finds an old friendship intact despite the passage of years and many absences.

If the earth is man's extended body, to be loved and respected as one's own body, those who do no greening of themselves will hardly bring about the greening of America. The idea of 'greening' involves color, flowering, freshness of spring, and, above all, respect for what is organic and vegetative as distinct from the mechanical and metallic.
