She ached. As if her spine were a zipper and someone had come up behind her and unzipped it and pushed his hands into her organs and squeezed, as if they were butter or dough or grapes to be smashed for wine. At other times it was something sharp like diamonds or shards of glass engraving her bones. Teresa explained these sensations to the doctor—the zipper, the grapes, the diamonds, and the glass—while he sat on his little stool with wheels and wrote in a notebook. He continued to write after she’d stopped speaking, his head cocked and still, like a dog listening to a sound that was distinct, but far off. It was late afternoon, the end of a long day of tests, and he was the final doctor, the real doctor, the one who would tell her at last what was wrong.
