A man and his wife were at a party. When a young woman walked in, the man told his wife very matter-of-factly: "Look, that's the mistress of our neighbour". His wife was rather shocked, but said nothing. When a few minutes later another another young woman walked in, he added: "And that's mine". His wife was silent for a long time. Then she said: "Ours is prettier".
