Just got back from a walk and watched a teen on a e-bike swerving in and out of both lanes on a two way street. A car passed him and the kid caught up with him at the next stop sign and started verbally confronting the dude. Guy got out of the car and was prob 6'3" 250 lbs. WTF was this 16-17 year old ,who was all of 5'7" 150 lbs, thinking? What is the endgame there and what explains this behavior? Feels like I just missed witnessing the shortest brawl of all time.
