I came to the riverbank. The sand underfoot crunches and sounds like my grandmother sighing. She is fond of chattering endlessly, although no-one understands her. If you ask, Grandmother, what did you say? She will look up absentmindedly and, after a while, say, oh, you're back from school? Are you hungry? There are sweet potatoes in the bamboo steamer. When she chatters it is best not to interrupt; she is talking about when she was a young woman. But if you eavesdrop from behind her chair, she seems to be saying. It's hidden, it's hidden, everything is hidden, everything... All these memories are making noises in the sand under your feet.
