I feel for ya. I really do. But you're 17 ! When you're my age you'd trash the car yourself for the opportunity to be your age again. I'd gladly trade you.
Trust me on this....it's only a minor setback that will just be an unpleasent memory before long, and in the years ahead you'll laugh when you think about how upset you are over what really amounts to just a bad moment in a long life full of countless other moments both good and bad. If i could be 17 again you could drive my new accord off a cliff and i wouldn't even blink.

And by the way. Don't even acknowledge gang types when they say anything to you. Just keep walking and don't confront them. It's a losing battle because all it takes is a few words and most of them will make it into something it isn't just to start something. And you can't win because they will go to whatever lengths thay have to to win including pulling guns. People like that are scum and need to spend thier lives in a cell or the ground. And I don't think i have to tell you that you should stay away from that park either !
