No sooner have they thought of Dresden than they can be on a train there; no sooner have they seen a dress than it can be in their wardrobe. They therefore have no opportunity to suffer the interval between desire and gratification which the less privileged endure, and which, for all its apparent unpleasantness, has the incalculable benefit of allowing people to know and fall deeply in love with paintings in Dresden, hats, dressing gowns, and someone who isn’t free this evening.
