eternal sunshine

I saw Eternal Sunshine of the Spotless Mind in the theater (March 2004), and at the end of the movie, I agreed with the main characters. I thought that I would make the same life choices over again if I had the opportunity, even if there was the promise of pain.

I saw it again tonight on DVD and wept at the ending. Is it because now there are memories I would rather have erased? Or is it because I, like Clementine, wanted my Joel to come after me and insist that we be together, no matter what the ending might be?
