Someone told me about unexpected feelings that arose after months of believing a relationship is over. Jealousy made an appearance, with its usual companions of love, desire and anger. Should we ever really think a relationship is 'over' because it's in the past (apart, of course, from the convenience of doing so to develop another one)? The first time I really thought about the impact of linear conceptions of time on emotion was via an episode of Deep Space Nine. Closer to home, though, there's Hall, E. T (1983) The Dance of Life: The Other Dimension of Time, London/Doubleday
