Charger + shopping cart + temper = cops

That sounds exactly like something I would do. And it's not the fact that the cart hit the car, you knew there was a chance of that even going to the store, it was the disregard shown by the people (term used loosely) after the fact.
I'm just average sized now (6 foot 205#) but this reminds me of something funny. When I was in high school, the biggest guy in the school hated me. He was huge, football star and older than me. I was probably 135# at the time. I always stood toe to toe with him every time he threatened me, even if I had to stand on a step to do it. He always backed down. I come to find out he ended up being a center guard for the Dolphins. Either proves my bravery or (more likely) my stupidity.
