"I was sitting right here a couple of days ago when these two guys started fighting. This one guy was just beating the hell out of the other one, so I jumped in.
I got them separated and just held the one guy there. He said he was done fighting, but I could tell that he was ready to go again. I think the scrap was about money or something. I knew if I let him go, he'd start punching the other guy, so I just held them there for his own good. Eventually the cops came and sorted it out. It could have ended up way worse.
That's the thing about people: you gotta look after them, even when they don't know how to look after themselves, y'know? It also helps when you've been training in Brazilian Jiu-Jitsu as long as I have.
