“For some people, the time differentials established in youth never really disappear: the elder remains the elder, even when both are dribbling greybeards. For some people, a gap of, say, five months means that one will perversely always think of himself--herself--as wiser and more knowledgeable than the other, whatever the evidence to the contrary. Or perhaps I should say because of the evidence to the contrary. Because it is perfectly clear to any objective observer that the balance has shifted to the marginally younger person, the other one maintains the assumption of superiority all the more rigorously. All the more neurotically.”
