When he was nearly thirteen, my brother Jem got his arm badly broken at the
elbow. When it healed, and Jem’s fears of never being able to play football were
assuaged, he was seldom self-conscious about his injury. His left arm was
somewhat shorter than his right; when he stood or walked, the back of his hand
was at right angles to his body, his thumb parallel to his thigh. He couldn’t have
cared less, so long as he could pass and punt.
