I was at my high school and getting out of a parked car. When I opened the passenger door to get out, I hit a moving car. I heard a thud and the driver and passenger of the moving car scowled at me and then drove away. Around a week later, the driver of the moving car comes up to me, claiming I made a big dent in the car. Am I at fault for the damages or is the driver of the moving car because after all, they did not stop to assess the situation and I don't know for sure that I caused the dent in that car, since they just drove off. That dent could have possibly occurred after and they are just blaming me for it.
