I was thinking, no doubt, of our nights in bed, of the peculiar innocence and confidence, which will never come again, which had made those nights so delightful, so unrelated to past, present, or anything to come, so unrelated, finally, to my life since it was not necessary for me to take any but the most mechanical responsibility for them. And these nights were being acted out under a foreign sky, with no one to watch, no penalties attached--it was this last fact which was our undoing, for nothing is more unbearable, once one has it, than freedom.
