Bad Karma

I wonder if there is a weekly quota on bad karma? If so I may have met my quota just now. Whoo Hooooo! The good news is that I am fine. Bad news, just got rear ended in a torrential downpour. The offender appears to have continued on their merry way without so much as a "Hello, how do you do? Here's my contact information and my car insurance." It really would have been thoughtful, don't you think?
