Time interval is a strange and contradictory matter in the mind. It would be reasonable to suppose that a routine time or an eventless time would seem interminable. It should be so, but it is not. It is the dull eventless times that have no duration whatever. A time splashed with interest, wounded with tragedy, crevassed with joy - that's the time that seems long in the memory. And this is right when you think about it. Eventlessness has no posts to drape duration on. From nothing to nothing is no time at all.
