Mustafa had thin blood. It was like being too short or too tall; nothing could be done about it. At night in the winter he needed extra blankets or he slept in the barn because the animals could keep him warm. But in the summer sun he came into his own and reveled in energy. His pores opened up and he could do anything. He carried bricks, shoveled camel dung, or swept away the sand without needing to rest, while his friends wilted in the shade.
