Before buying my house, I used to have to park the car in the driveway. Usually it was always parked farthest in since it saw the least use, but this time I felt lazy and didn't want to juggle all the cars around, so I parked behind my sister's Crapali---er, Cavalier.
For whatever reason at that particular moment, instead of putting the car in neutral and pulling the e-brake as soon as I parked like I
always do, I left it in gear and just lifted my foot off the clutch...like I always do when I put the car in neutral and pull the brake. Instant lurch and realization of what was happening, tried to get the clutch in and foot on the brake, but it was too late and my car's recently detailed nose ended up in the rear of a (thankfully also silver) Chevy. The point of my nose was aligned with the ridge on the Cavalier's bumper cover that surrounds the license plate, so it was a good shot for travelling only a few inches. The Cavalier looked untouched. I now have a very small dimple on the bumper from the impact and plenty of spiderwebbed paint in about a 6-inch radius.
You can bet I was m-fing myself for a while after that, and I notice it every time I am anywhere near the front of the car.
