Mrs Muncaster, a tiny old lady, lived alone on top of a steep hill. One morning, as she was pushing her mower briskly down the precipitous lawn, a young man screeched his car to a halt in the street below.
"Lady," he shouted, "You scared me half to death charging down the hill after that lawnmower. You shouldn't be doing such a thing at your age. Don't you know you could run off the hill and be killed?"
"Young man," said she, "go home and search your newspapers. Just see how many 86 year-old women are killed running their lawn mowers off hills. Then see how many young men are killed driving their cars down the street."
Mrs. Muncaster returned to her mowing, and the young man drove thoughtfully on.
