I have to agree with the last reviewer: I definitely felt a reference to yin and yang, but there is also a discord that I felt between the two, like they could never fit together nicely. I felt like the narrator was aware of the sadness of his situation, but that he had come to terms with it. I don't think the narrator will leave this woman although he is not as connected to her as he wishes he could be. I pictured him looking at her through a window as she set out to get the rice. Maybe he's sipping tea, maybe he's just blinking slow and looking at this woman that is both his and not his. Fantastic.
-- i feel that with exquisite and infinitely poetic images you brought out a rather perplexing dimension of the yin and yang equation... -- it seems to me that the narrator of this piece feels abandoned but doesn't quite know why... or the reason hasn't been shared with him yet (if there is one)...
