More importantly, there are people I know for whom the clock never wound down. And to examine another facet of my opposition, for me, there are a couple old loves out there for whom I feel the watch still ticks, but it just isn't so close to my heart. And the one I've had for a while now, it seems like it's solar-powered or something (with batteries for nights, dark rooms, and rainy days!), really I'm a human and can love, and I can keep things going.
I'm a BIG fan of this Romantic love, though, and believe it's the most important, and I do know that it can run out, and I do know it can be different for different people. I'm glad to have Sandburg (and you) on my side, as far as that goes. I wouldn't claim mine or Sandburg's experience of romantic love was better or worse than the other's (though I do have a prejudice against those who take it less seriously, preferring for example "automatic compassion", or even worse, a sort of cynicism that never allows it to bloom beyond an ironic pose in a game of "poker", if you know what I mean).
