I can't stand people parking next to me even though I park really far away.

Even though I don't have a new XF, about a month ago I got an '04 gray coupe, and so I'm in love with it. I took it to school and parked FAR far away and so as I'm leaving class at night and walking to my car I realize that there's someone parked really close to my car and I got freaked out a little, and so they open their car and this girl jumps out and goes "is this your car?" I was thinking, don’t you see me opening my trunk. She goes "I just scratched your car" as soon as she said that I FREAKED OUT! " I was like come on now, what the *F***K!@#!@!!!" so she goes on to tell me that she was leaving me a note but had planned on running away. So I couldn't really assess the damage since it was pitch black, but the next day she had scratched the rear bumper pretty badly. What an a_hole! Total damage costs about $450, which she's paid $200 so far. Ughhh it's just annoying. to top it off, she goes, "I wasn't really paying attention".
Well no F***kin' kidding!

It annoys me so much and I'm so glad to vent here, because when I keep telling my fiancé how much it annoys me, he probably thinks I’m obsessed with my car (which I am ).

So what to do about these morons who ding our cars??? I want revenge!!!
