I was riding my bike down a hill in my city one night and two policemen stopped me at their speed trap. They asked me how fast I was going - 63 km - and congratulated me on the accuracy of my speedo. They then asked me why I was not driving a car and as I was a woman, wasn't it dangerous to be be out at night on a bike. I said I did not drive a car. They then asked me my occupation - I said "an economist". One of the policemen said "That's why she's riding a bike - she's economising"


一天晚上在我在小城里骑着自行车从一个小山下来，被汽车测速监视区的两位警官拦住了。他们问我的时速是多快——63公里——并称赞我的速度计时表是精确的。他们问我为什么不开车，作为一个女人晚上晚上骑自行车上路是不是会危险。我说我不开车。他们又问我是干什么的，我说是经济学家。其中一个说：“这就是她为什么不骑自行车，经济学家精打细算。”
