Civil Duty?

Just this past week, someone hit my friend's car and didn’t leave a note. Now, this wasn’t just a little scratch from parallel parking or something, but rather an enormous dent with chipped paint everywhere. This caused me to think about people’s civil duty, or lack there of. I could never hit someone’s car and not leave a note. I would have the worst conscious over the situation, and wouldn’t be able to live with myself. My friend now has to pay tons of money, for someone else’s mistake. The bigger picture here is that, if humans do what there supposed to do, the world will continue to go round. Its when people, like Mr./Ms. Hit and Run, don’t live up to their civil duty that the system gets thrown out of whack.
