Thomas had driven a bus for thirty-eight years, and his body had learned the shape of the driver's seat the way a river learns the shape of its banks. He knew every pothole on the crosstown route and every school crossing by heart. When he retired at sixty-four, the city gave him a small plaque and a cake in the depot break room. He meant to. He had loose, pleasant plans: long mornings with the newspaper, afternoons in the garden, Sundays with his daughter's family. What he had not planned for was how quickly his legs would forget how to be legs.
It began quietly, as these things often do. One warm afternoon in late spring, Thomas settled into his armchair after lunch, intending to read for an hour before tending to the tomatoes. The chair was deep and forgiving, and the book was good, and the hour stretched into two, and then into three. When he finally stood, his legs felt strange beneath him — heavy, as though he were wading through shallow water, and faintly swollen around the ankles. He frowned down at them. His socks had left deep rings in the skin. He walked to the kitchen, poured a glass of water, and told himself it was nothing. He had sat too long. That was all.
But it happened again the next day, and the day after that. Each afternoon, the heaviness returned, a dull, dragging feeling that made the short walk to the garden gate seem longer than it should. His left leg felt worse than his right, and once, when he pressed a thumb gently against his calf, the skin stayed dented for a moment longer than he liked. He thought of his years behind the wheel — ten hours a day, his feet working the pedals while the rest of him stayed still. He had always joked that driving was the only job where a man could travel fifty miles and never take a step. Now the joke felt less funny.
Thomas was not a man who frightened easily, but he was a man who read the health pages of the newspaper with attention, and he remembered an article he had read months earlier about clots that formed in the deep veins of the legs. He remembered the name — deep vein thrombosis — and the warning that a clot could break loose and travel to the lungs, where it became something far more dangerous. He remembered the list of signs: swelling, warmth, redness, pain. He looked at his own legs again. They were not red. They were not hot. But they were swollen, and they were heavy, and the heaviness did not fully leave him even after a night's sleep.
His daughter, Maria, noticed before he said anything. She came by on Sunday with the grandchildren, and while the children played in the garden, she watched her father cross the kitchen, pausing with one hand on the counter to let his legs catch up.
"Pa," she said, in the tone she had used since she was sixteen, "how long have your legs been like that?"
Thomas shrugged, the way fathers do when they do not want to worry their children. "They're just tired. I sat too long yesterday."
"Yesterday and the day before, and the day before that," Maria said. She was not scolding him. She was counting. "You spent your whole working life sitting, Pa. And now you spend your afternoons sitting. When did you last walk further than the garden?"
He opened his mouth to answer, and found he could not remember. That bothered him more than the swelling. He had always been a man in motion — steady, reliable motion, the kind that had carried a bus full of people safely through a city. Now his world had shrunk to the distance between the armchair and the kitchen, and his legs were telling him about it in the only language they had.
That evening, after Maria and the children had gone home, Thomas sat at the kitchen table with the telephone in front of him and the doctor's number written on a scrap of paper. He had always disliked making a fuss. He had driven through snowstorms and traffic jams without complaint, and he told himself that a pair of heavy legs was hardly a crisis. But then he thought about the article again, and about the warning it had carried, and about the way his grandson had looked up at him in the garden that afternoon and asked why Grandpa was walking so slowly. He did not want to be the kind of man who ignored a warning because it was inconvenient. He picked up the telephone and made the appointment.
The receptionist offered him a slot on Thursday morning. He wrote it down carefully, in the neat handwriting he had used for route logs, and stuck the note to the refrigerator with a magnet shaped like a bus. Then he stood, walked slowly to the garden gate and back — a distance of perhaps thirty steps — and felt the heaviness settle in his calves like wet sand. He did not panic. He did not diagnose himself. He simply decided, as he had a thousand times behind the wheel, that when something on the dashboard lights up, you pull over and get it checked. Thursday could not come soon enough.
