We walked by a small confrontation in NY the other day. I wouldn't really call it a fight. Roughly, here is what we saw/heard.
Guy 1 was yelling something about he told Guy 2 to move. Rather aggressively, but I'm not sure if it was because Guy 2 was yelling first (we didn't see the beginning).
Guy 2 said something half yelling, half laughing.
A little more argument we couldn't hear (we'd walked by).
Guy 1 walks back. Who knows what they said.
Guy 2 moves to punch Guy 1.
Guy 1 dodges and pushes Guy 2 into the trash/recycle bins.
End of "fight". Ok so it wasn't really a "fight", but I thought it was interesting mostly because of "push" kind of ending the fight. No idea if the guy pushed was hurt at all, but apparently they both decided that was a sufficient ending and the pusher probably won.
Also, we had total onlooker/standby inaction/curiousity. Didn't know what to do. It all happened and ended rather quickly. No one seemed hurt. No need to call the authorities. Still not sure who was more at fault.
