If memoir is sculpture, where writers must strip away the unnecessary to find the shape of the story, then it is my memory that wields the knife. Memory chooses certain scenes and impressions. Memory snips and stores fragments and shadows. Memory does not follow the rules of chronology or of rational cause and effect. Memory puts any old thing next to another for its own reasons and may preserve for example, the dance of a courageous vole in perfect detail, while jettisoning a crucial conversation with a friend who is now gone. Try as I might to recall that moment with my friend, memory carved it away, leaving only shavings on the floor, which I crushed into ever smaller pieces as I paced back and forth, studying what I had left to work with.
