"‘It was too perfect to last’ I am tempted to say… But it can be meant two ways. It can be grimly pessimistic - as if God no sooner saw two of his creatures happy than He stopped it. …But it could also mean ‘This has reached its proper perfection. This has become why it had in it to be. Therefore of course it would not be prolonged.’ As if God said, ‘Good; you have mastered that exercise. I am very well pleased with it. And now you are ready to go on to the next.’"
C.S. Lewis, ‘A Grief Observed’
