30 years ago I was driving home after work. It was dark and the dog darted out in front of my car from in between parked cars. I did slam on my breaks but I heard a bump. I immediately got out and began looking for the dog, who was nowhere to be found. I knocked on doors but it was futile.

I felt like you do. But there are certain times when things like that happen and there's really nothing you can do about it.
