Since Dad had acquired all these accessory parts—the external kidney, the external lung—he had become a rather complicated piece of machinery, like a high-end TIG welder, that could not be operated by just anyone. John, who had come back from Vietnam with bilateral below-the-knee amputations, was more than comfortable with prosthetic technology; he had read all the manuals and understood the functions of most of the knobs, so he could take over responsibility for the machines at times like this.

"I’ll walk you to your car," he announced, and she grinned sweetly at his euphemistic ways. "Turkey this afternoon?" he asked.
