Something similar happened to me when a woman backed into my car in a parking lot, hitting the side of my car. I was not even moving. She yelled at me like "did you just hit me, there are kids in this car, you're lucky there's not damage". I was like 18 or something and totally froze and then was like, no, you hit me, but she didn't believe me. At least she didn't try to call the police or something. She was probably in her 30s or 40s, though, just not paying attention I guess.
