The moment you carry out any of your dreams or your fantasies - travel around the world, climbing a high mountain, buying a new house, writing a novel, carrying out a sexual fantasy, traveling to an unknown country - the moment you carry out your dreams, it's always, by definition less perfect and rosy than it had been as a dream. This is the nature of dreams.
Amos OzTwo children of same cruel parent look at one another and see in each other the image of the cruel parent or the image of their past oppressor. This is very much the case between Jew and Arab: It's a conflict between two victims.
Amos Oz
