Murder. . . or suicide?

I killed a bird today. Or rather, my car did. I was driving along minding my own business (singing along to the Rent soundtrack of course) and these birds flew across the road. I didn't really slow down because I figured they would scurry in mock terror to their homes in the sky. Not for one sad little fellow though. He flew really low and I didn't have time to stop, so I just heard this little thud and in my mirror I could see a stream of feathers in my dust. On one hand, I feel really guilty. On the other hand, I was thinking "Damn stupid bird. Why didn't you get the hell out of my way?" I thought there was some unwritten law that stated all birds should get out of the way of automobiles and we automatically have the right of way. I choose to believe the bird committed suicide. Seriously, it's like he flew right into my car and wasn't even trying to avoid it. Stupid bird.
