The trick in "So Proud" is that a woman is impregnated by her husband. She gives birth a couple days later to a couch. This happens again and again and she gives birth to various pieces of furniture. The husband sells the furniture, their children, for money.
Shearman's prose allows quick and easy reading while still entertaining.
The next time she fell pregnant he didn't get angry at all. On the contrary. He brought her cups of tea, kept asking how she was, wanted to make sure she didn't overexert herself. And he'd nuzzle her swelling belly, kiss it, and whisper to it - what are you going to be when you grow up? What are you going to be?
Then she gives birth to more furniture. On the surface, this sounds kind of dumb, but somehow Shearman makes the story work.
