People are nuts out there. Dial 911 is the first thing you should've done.
Remember that case or road rage in Cali? This guy somehow got this lady to pull over because she cut her off. He reached in and grabbed her little dog and threw it on the highway where it was killed. Why? Because she cut him off and I think it was by accident. This world is getting worse and worse and getting revenge on someone because they cut you off is Satan's way of thinking. He wont be happy until everyone is killing each other for no reason at all.
If I was in that situation I would think that I would call 911. But she was really scared and some times you can't think straight like that. We all gave her the speech about calling the police if it ever happened again. you are right about satan, too.
