Sorry, but to be honest, I have no sympathy for people who acted as you did. Life is far too short for anyone to become aggressive over a silly parking space. Perhaps it is time you realised that you obviously are "this kind of guy" and you need to work on changing your attitude! There is no point in trying to make excuses to yourself. You did what you did and now must stand and take the consequences. What if one of your punches had landed that person in hospital with brain damage or worse? There is no excuse for being aggressive, nor is there an excuse for anyone to use a hammer on another person! You will just have to sweat it out and take whatever punishment you get. But do try to get some good out of this experience ... NEVER let yourself get into that kind of mental state again! The same applies to the others who were aggressive. So tell me ... was the parking space worth all this?????
