You did the right thing by driving away. Getting out and confronting an “older woman” that was obviously in an altered state of mind would have been a no win scenario for you. I mean really, what would have happened? What could you have done? Throw a rubber duck at her and escalate the situation? Wrestle her to the ground? Punch her in the nose?
If she had damaged your vehicle, it still would have been better to stay in your rig, call the police and let them handle her. Maybe it’s the fact that it was an “older woman”, had it been some guy, maybe I would have thought differently, but probably not if myself or my family was in no danger from the incident.
I do know that I wouldn’t put myself in an uncomfortable situation that could possibly turn physical with an old woman.
