Some history-making is intentional; much of it is accidental. People make history when they scale a mountain, ignite a bomb, or refuse to move to the back of the bus. But they also make history by keeping diaries, writing letters, or embroidering initials on linen sheets. History is a conversation and sometimes a shouting match between present and past, though often the voices we most want to hear are barely audible. People make history by passing on gossip, saving old records, and by naming rivers, mountains, and children. Some people leave only their bones, though bones too make a history when someone notices.
