Quick Karma
About ten years ago, I was driving home, and there was a car in front of me that was changing lanes, speeding up, slowing down, starting to change lanes, then ooching back over to another lane – like you'd imagine a drunk would drive.
I was getting more frustrated and more righteous with every passing block. Finally I pulled alongside the car and was glaring at the driver – who turned out to be someone's grandmother. While I had my head turned to perfect my glare, I rammed into the back of the car in front of me.
So while I was pulling over to the side of the road to square away the details of insurance, etc., the little old lady sailed right past me.
That was a $1,600 lesson – handle my own business.
