I hope this wasn't a choice, bad or otherwise. Sounds like you weren't in control.

And if you can lose control, and get repeatedly violent with a random non-threatening stranger at the zoo of all places.. and your response was to run away, and take no responsibility for it?

I'm sure you mean well, and are generally great. But anger of this magnitude over something so small as a parking spot? How are you going to prevent it from happening again?

I'm not trying to make you feel worse, but what exactly did you learn from it? Why do you think punching someone over a parking spot was even in the realm of possible outcomes for you in this situation?

He is filling with his insurance and therefore will file a police report. You're going to pay for both cars damage, you're going to pay for his medical damage, you're going to be served on assault / battery charges.

And then you should top all that off with some therapy sessions. I'd say you're in it for $8000-$10000.

It seems like this is a recurring theme though. A couple of days ago you had an incident that didn't lead to physical violence but it sounds like you went in looking for trouble. I get being pissed that someone parked too close but you could have easily asked politely if he would have minded moving his vehicle for you to get into yours and you more than likely would have had better results. And even if not at least you did all you could in a respectable manner. And then again today you went and started shit and DID end up inciting violence. You hit a guy twice causing him to hit another vehicle. What if there was a kid walking between vehicles? What if it wasn't minor damage? Again, I get being upset but YOU made the choice to hit the guy. Every day you and I have the ability to be the kind of person we want to be and in both instances you decided to be an asshole and to be honest, if he did get your license plate number there will be repercussions for your actions. You left the scene of a crime that YOU CAUSED. Not only that but you assaulted someone. You fucked up big time. I do hope that you learned from this and if you haven't yet you will. Because this guy's insurance company will be filing a lawsuit against you as well. This isn't a small fuck up, ya done fucked up big time. If you want to set this right it's time you pay the piper and talk to the police yourself.

Yes you do. You punched him in the face twice. One day you’ll do that to someone this will have no issue making your children fatherless.
