| Last night I was driving from Harrisburg to Lewisburg, a 1 of about eighty miles. It was late and I was in a hurry. However, if anyone asked me how fast I was 2 , I'd say I was not over-speeding. Several times I got 3 behind a slow-moving truck on a narrow road, and I was holding my fists tightly with 4 . At one point along an open highway, I 5 a crossroad with a traffic light. I was alone on the road by now, but as I 6 the light, it turned red and I braked to a stop. I looked left, right and behind me. Nothing. No cars, no suggestion of headlights, but there I sat, waiting for the light to 7 , the only human being for at least a mile in any 8 . I started 9 why I refused to run the light. I was not afraid of being 10 , because there was obviously no policeman around, and there certainty would have been no 11 in going through it. Much later that night, after I 12 a group of my friends in Lewisburg and climbed into bed near midnight, the question of why I'd stopped for that light 13 me. I think I stopped because it's part of a contract (合同) we all have with each other. It's not only the 14 , but it's an arrangement we have, and we trust each other to 15 it: we don't go through red lights. Like most of us, I'm more likely to be 16 from doing something bad by the social convention that 17 it than by any law against it. It's amazing that we ever 18 each other to do the right thing, isn't it? And we do, too. Trust is our 19 preference. I was so 20 of myself for stopping for the red light that night. | ||||
