Don't ever think that animals don't understand. Not 30 minutes after running over that little chipmunk, I get up to go to the kitchen for something to drink. I look out my glass sliding door and I see this little chippy sitting on the edge of the curb just staring at my car. He just happens to be staring at the exact spot on the car that killed the other chippy out in the country. Coincidence? I don't think so.
