seoul subway. the old lady got on at apgujeong. she had two enormous duffel bags strapped onto a dilapidated two-wheel baggage cart, with some plastic bags on top. it was almost as tall as she was. it fell down on the floor of the subway car. one of the metal pieces of the baggage cart's frame had broken, and she was struggling to improvise a way to connect the two ends, separated by 10 cm of bulging black duffel. she had a jar of something… and was pounding on one end, while trying to hold down the bulge. a tiny, well-dressed woman began to help… then a kind-looking man in a brown suit jacket got involved… then a tall man in a nylon pale green ski jacket started helping too, and he was talking in soft, gentle tones to the frustrated old woman. here in the vast city, these people were showing a unwonted kindness to the old woman, and to each other. others looked on: in bemusement, amusement, or sheer pleasure at seeing such an odd drama unfolding. various solutions to the problem of the separated metal parts were tried, one after the other. people were offering advice or suggestions… it was so interesting. there was a point when the problem seemed solved. i exchanged grins with the kind-looking man in the brown suit jacket. but it was a false finish. the woman began tugging her cart, and the pieces separated again. second round… the man in the ski jacket used a key from the key-ring attached to his cellphone to widen the aperture of one of the rusted metal ends of the cart, and successfully forced the metal part in, again. the small well-dressed woman sat forcefully on the bulging pile, to get the two ends closer together. the old woman pounded on the bottom end with her jar, while the kind-looking man held things in place. at last, the cart seemed well-fixed, again. they stood it upright, while the entire subway car barely refrained from breaking out in applause.
