Replying to Starting fights with people in cars

alright, so coming home from gamestop and on the way some guy was on his phone with his kids in his car. my friend yelled "get off your phone" out the window. Now hes on our ass and trying to pass us on our right, and the next stop light is right next to a cumberland farms and he hops out the car and yells " you wanna fucking go!?" lol cant lock my car so we had to panickly wait for the green and as we sped off he kind of ran after our car. lol didnt really need to get in a fight then, i have graduation tmrw. it wouldve been a hell of a story though.

sparknotes: guy gets angry over us telling him to get off his phone and trys to start a fight with us
