Instead, my mother simply went back down to our apartment and called the landlords, "My upstairs neighbor has just threatened the lives and health of myself and my family. I no longer feel safe with him up there.". The damage a soccer ball can do to a car, other than a dirty smudge, is minimal. If it could do serious damage, I would question how that car would fare in a real accident. Soccer might not be the best sport for the drive, I agree. A basketball hoop or two might involve less bouncing of balls against cars.
