All sensible people know that vanity is the most devastating, the most universal, and the most ineradicable of the passions that afflict the soul of man, and it is only vanity that makes him deny its power. It is more consuming than love. With advancing years, mercifully, you can snap your fingers at the terror and the servitude of love, but age cannot free you from the thraldom of vanity. Time can assuage the pangs of love, but only death can still the anguish of wounded vanity. Love is simple and seeks no subterfuge, but vanity cozens you with a hundred disguises. It is part and parcel of every virtue: it is mainspring of courage and the strength of ambition; it gives constancy to the lover and endurance to the stoic; it adds fuel to the fire of the artist's desire for fame and is at once the support and the compensation of the honest man's integrity; it leers even cynically in the humility of the saint. You cannot escape it, and should you take pains to guard against it, it will make use of those very pains to trip you up. You are defenseless against its onslaught because you know not on what unprotected side it will attack you. Sincerity cannot protect you from its snare nor humour from its mockery.

Her tears were partly tears of happiness, for she felt that the strangeness between them was gone. She loved him now with a new love because he had made her suffer.
