According to Osho, the 'difference' between a politician and a lady is a comic inversion: as Shaw quipped, each says one thing and means another in opposite directions. But the deeper point is that both are masks of a cunning society. In true innocence, labels like lady and politician vanish; only simple, honest human beings remain.
Both are playing word games to keep up appearances; if we live simply and honestly, those labels aren't needed.
