She hit you, you tried to help her get out of traffic so that the two of you could discuss the legalities, she showed a frightening lack of control of her car, and she left. She left.
Whatever you do, do not drop the charges. I don’t care what age she is, she should not be driving in such a state. If I ever show that kind of lack of control and lack of consideration, I pray that it doesn’t take someone getting hurt before I get the book thrown at me.
Plus, she needs to take responsibility for her actions. She was involved in a hit and run, and nothing excuses her from that fact.
On a side note, she complained that the accident had ruined her dinner? Holy frell, you had a child in your car and she could not care less about the Sprout’s wellbeing. That alone would remove from my mind any thought of letting the hit and run aspect of the accident slide.
