“Just accept as a fact that everyone of any emotional importance to you is related to everyone else of any emotional importance to you; these relationships need not extend to blood, of course, but the people who change your life emotionally - all those people, from different places, from different times, spanning many wholly unrelated coincidences - are nonetheless 'related'. We associate people with each other for emotional not for factual reasons - people who've never met each other, who don't even know each other exists; people, even, who have forgotten us.”
