glad you ok bro, just make sure all is alright as adrenaline, shock, and anger can mask injuries. tomorrow you may find a few sore spots.
now the driver, stuff happens and accidents happen for many various reasons. its how people handle it after it happens. way bogus that she took off like that. what i would do is take a drive back to the complex to see if you can find the car, once found call the cops. or channel your inner michael douglas in falling down and go ape s**t on her car.
congrats on handling it level headed!
