Soo like two months ago, my dad and my sister were practicing driving in an abandoned parking lot. My sister, being a new driver really didnt know how to brake, so she almost hit a crossing pedestrian in the lot. This pedestrian then continued to curse my dad and sister off. My dad apologized and said sorry, and got back in the car. after this guy continued to call my sister a "dumb bit**) my dad got out of the car and walked towards him and started to threaten him, This guy started walking up to my dad, and my dad ran at him and the guy turned around and ran away, proceeding to drop his food and drink on the way. My dad got back in the car, and my sister continued to drive.
