I never knew what sad work the reading of old-letters was before that evening, though I could hardly tell why. The letters were as happy as letters could be -- at least those early letters were. There was in them a vivid and intense sense of the present time, which seemed so strong and full, as if it could never pass away, and as if the warm, living hearts that so expressed themselves could never die, and be as nothing to the sunny earth. I should have felt less melancholy, I believe, if the letters had been more so.
