women will do that to you. it starts with a shovel is a shovel. next a power tool will become just another power tool. finally, a car is just a car, so just pick one as long as it holds the wife, kids, and the dog. it will be simplest to consider getting a new girlfriend. don't worry about it too much. accidents happen. at least you know who did it and you didn't just find it with the scratch. hopefully, you can get it fixed, and move on (to the next girlfriend).
