When we're young, everyone over the age of thirty looks middle-aged, everyone over fifty antique. And time, as it goes by, confirms that we weren't that wrong. Those little age differentials, so crucial and so gross when we are young, erode. We end up all belonging to the same category, that of the non-young. I've never much minded this myself. But there are exceptions to the rule. 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.
