Anywhere I've ever been it's never been a one on one thing. I go to the bars, the events downtown, festivals, etc. People, cliques, gangs, show up with numbers at events. The only way you'll find a guy by himself is if he's on a date.
This dual stuff that people seem to be coming across I haven't seen it outside of high school or an actual fight gym. Perhaps I am the outlier in the discussion.
Whenever we go out, I'm always asked am I packing. Always. That question comes from competitive fighters as well. None of us go in expecting a dual, people don't want to fight you head up in self defense situations.
I've even had friends ask me, when I tell them what I'm doing in practice, does my training teach me how to dodge bullets? lol
You guys can carry on without me I guess lol. I just have different experiences with "self defense". Combat sports help readiness, yes.
