Out in the field I threw myself wholeheartedly into a project to build a school in northern Mali, three hundred kilometres from Bamako, near the former capital of the Songhai Empire.With a naivety which now brings a smile to my lips, I could already see myself as a schoolteacher surrounded by dozens of orphans of all ages, staying on after lessons to take them down to the Niger and watch them have fun, jump, swim and play hide-and-seek while the great red disc of the sun dropped slowly into the river, where bare-breasted washerwomen stood waist-deep in the water, singing and laughing as they beat wet clothes over stones with wooden sticks that made a dull, slightly muffled thud. I myself would bathe the youngest children (Would I have known how to? Is being born a woman enough for that skill?), supporting the toddlers streaming back with one hand and soaping him with the other. Then I would tell him to wriggle his arms and legs in every direction in time to the washerwomen’s jubilant song, or do a slight variation on this the way African mothers do: bunching the child’s arms and legs over his tummy, then suddenly letting them go and smothering his silky soft naked body with kisses, as if he were my own baby, my child from Peking who, as he grew up, had changed skin colour—a frequent phenomenon in dreams, where physical appearances go unnoticed, can be modified and are often interchangeable.
