One rainy day, Bill was riding his bicycle when the mail truck in front of him suddenly stopped. The crash left him paralyzed from the chest down. His autonomy, or what's left of it, comes from voice controls that let him lower and lift the blinds in his room or adjust the angle of his motorized bed. For everything else, he relies on round-the-clock care. Bill doesn't know Anne, who has Parkinson's disease; her hands shake when she tries to apply makeup or weed the garden.
