"Filmmaking to me have always been like being in a love relationship, you go through a series of intense experience, you laugh, you cry, you empathize with each other and when the film is finally done, you feel a sense of relief concocted with melancholy. The film is done, the love relationship is over. We started to reminisce, to hold on to what was left. Something stops and starts."

--- Royston Tan (stolen from his blog)

sounds exactly what happened to us for production.
