omg im so sorry, i would be LIVID(seriously i would probably beat someone to death if they did that to my car..) just yesterday in a parking lot, i was driving out and someone was backing up and didnt see me, so i reversed, and he kept backing up(i didnt even have time to honk or else i would have lost those few valuable seconds to put the car into reverse and he would have hit me) either way, i, thank god, managed to have him not hit me, but still, i couldnt sleep at night i was so pissed
