" He fell over frequently, but he never cried, though the ice was hard, the hardest surface his bones had ever met. He taught himself to laugh instead. Laughing was a bit like crying. It was a strange convulsion; it just came from a different bit of your mind. The trick was to move the crying out of that bit and let the laughter in. And so he'd pick himself up and carry on, laughing. "

― Rose Tremain , The Gustav Sonata
