OK, I always park at the back of the lot, against a curb, coz I got a new paint job and i'm sick of my doors getting banged up...why are there so many careless dumbshits in the world who open their doors into mine?!?! People who can't respect other people's property and park too close to the next car shouldn't be allowed to, uhhhhh, PARK!!!!
done ranting, back on topic
If I understand right, she hit some other car and didn't take much notice, because she was in too much of a hurry, and then after the fact did not care too much about whether there was any damage.
She may say she'll be more careful in the future, but that's not good enough.
She can say that, but it probably won't make any difference until she realizes what she's doing wrong.
She has to *learn* how to drive and park safely. Maybe you can try and help her out, who knows...
My car doesn't have a chrome bumper. It's not a big ass SUV with a push-bar. If anyone hit it in the lot, it would surely cause several hundred dollars worth of damage -- and if I saw them hit me and then try to ignore it, I'd probably go crazy...
I mean I'm not psycho but you would definitely witness a very angry, fearless hyena

and I would hold her and her insurance accountable.
My best advice would be to help her learn to park more safely, and to realize it and take responsibility if she damages someone else's vehicle.
