I looked left，right and behind me.Nothing. No cars，no suggestion of headlights，but there I sat，waiting for the light to ____，the only human being for at least a mile in any ____.
I started ____ why I refused to run the light. I was not afraid of being ____，because there was obviously no policeman around，and there certainly would have been no ____ in going through it.
Much later that night，after I ____ a group of my friends in Lewisburg and climbed into bed near midnight，the question of why I'd stopped for that light ____ 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 ____，but it's an arrangement we have，and we trust each other to ____ it：we don't go through red lights. Like most of us，I'm more likely to be ____ from doing something bad by the social convention that ____ it than by any law against it.
