She wаs buxоm, well-rоunded, cоmpаct аnd sturdy—so trim in her movements that in walking, turning, bending or climbing there was no awkwardness at all. She was like a brand-new boat: neat and shapely, gliding with ease, not a loose joint anywhere. Everything amused and intrigued her; she loved to gossip; her bright, restless, deep black eyes missed nothing as she walked to the [river], pitcher on her hip, parting her veil slightly with her finger. [The other] had been her exact opposite: unkempt, sloppy and slovenly. She was utterly disorganized in her dress, housework, and the care of her child. She never had any proper work in hand, yet never seemed to have time for anything. [She] usually refrained from comment, for at the mildest barb, [the other] would rage and stamp and let fly at her, disturbing everyone around. Each…was matched by [their partner] to an extraordinary degree. [He] was a huge man—his bones were immense, his nose was squat, in his eyes and expression he seemed not to understand the world very well, yet he never questioned it either. He was innocent yet fearsome: a rare combination of power and helplessness. [The other], however, seemed to have been carefully carved from shiny black rock. There was not an inch of excess fat on him, not a wrinkle or dimple anyqhere. Each limb was a perfect blend of strength and finesse. Whether jumping from a riverbank, or punting a boat, of climbing up bamboo-shoots for sticks, he showed complete dexterity, effortless grace. His long black hair was combed with oil back from his brow and down to his shoulders—he took great care over his dress and appearance…he was not unresponsive to the beauty of other women in the village, and was keen to make himself charming in their eyes.
