I seriously don't care what condition my vehicle is in, whether the paint is nice and new or faded with a little rust, you DON'T mess with my vehicles. Don't get me started on door dings, there's no reason you need to park that fricken close!
At a snowmobile dance once, a ******** that I (at best) didn't care for parked next to me and dinged me on purpose because he knew it pissed me off. Although I left before he did, I know he came out to tires needing air on one side of his truck. I guess it must have been from a valve core removal tool someone keeps in his truck with the rest of his HVAC tools. And I'm pretty sure the core was where it needed to be as well.
And don't think this comes from just a ding, in high school he crawled underneath my 76 Monte Carlo and cut the wires to the starter while at a party in the woods. I managed to jury rig it to get home so I could repair it, but I didn't forget his fu**ing with me. After cutting it, he and a few of his friends were pushing me around which made trying to get home difficult, but I did and I remembered. The deep ding purposely driven into my truck was the last straw.
