If there's an argument between two people, is it a big deal if one person grabs the other person by the arms (facing each other) and pushes that person hard enough to move them a few paces backwards? The grab and push is an attempt to take an argument happening in public to a slightly different space that is perhaps marginally more private?
The grab and push don't hurt nor cause any physical harm (although the person being pushed resists, so it MIGHT be possible that without the resistance the person might have bumped or hit something).
Relatively minor on the physical altercation scale, heightened emotions etc. Is it just a blip?
This is not an argument between a couple.
