WhiteZoom - sorry, I didn't see the part about the damage that fat-ass woman caused to your car.
But I still can't advocate keying up her ride. A woman like that deserves a good talking to, and the police need to be called to file a report so she could pay for the damage she caused.
Sure, revenge is sweet, but in the end don't you just want your car fixed? I think the best revenge in the world would've been hearing that biotch admit to the cops that her fat ass caused a big dent in your car. Her embarrassment alone would've been worth it.
Violence toward these inconsiderate asswipes won't teach them anything, unfortunately. It can only lead to more issues for you in the end - if you had gotten caught, you'd have had to pay or your damage AND hers. Sorry for sounding so law-abiding and parental, but I have to go back to something I learned a long time ago: You can't always be so damn hard on someone who is an asshole, because at some point YOU will be the asshole. Nobody's perfect. Get pissed, but just roll with it.
And MP3 girl - that story REALLY hurts. I would've done whatever I could to let any prospective customers of that "stealership" know that they will be ripped off.
