I used to be fearless and then got old. One night years ago I was sitting in my car getting high and the car was turned off. I saw a group of kids walking up the block about 100 yards away. One had a bat and was taking swings at cars, hitting mirrors, windshields and headlights.
There was a time I would have got out of my car and challenged them. That night I turned on my car (which startled them and the bat was hidden) and I drove home and called the cops. I gave them the street name and direction the kids were walking.
I knew I had crossed a boundary in my life that night
