All the more reason not to fight some rando off the street.
It doesn't matter to me. I've sparred against strangers before.. But I always had my defense fully activated even if my attacking power wasn't. When I was in my 20's I worked at a community center where a guy new muy thai. My friend/ co-worker and I used to spar during the down times, and this one guy wanted to join as well. His bragged about his Muy Thai. I set the rules, He used a low kick to my leg but I raised my knee the kick went under. The kick was hard as spun around and tried to take my head off with a spinning backfist. My defense was tight. His fist fell on my guard. He thought he could suck punch me, He failed. I corrected him. He did it again after the first warning. His spinning back fist failed again. I warned him again.
Twice I stopped his serious attacks with ease, it didn't even scare me, make me mad,. I was calm and that probably made him nervous. My second warning was harsh. I told him that I will return the favor if he tries it again. He never did. He also stop sparring with me. So out of all of this what did I gain?
Here's what I gained.
1. I have a video of it somewhere it's on VHS if I can find it I will share it.
2. My self-defense skills using Karate that day was verified as still valid (I was taking Jow Ga back then but didn't know how to fight with it, so I had to fall back on my Karate).
3. I had a witness (my friend) there and he was able to see me validate all that I was teaching him.
4. Self-reflection. I now had a better idea of my abilities not just in a friendly sparring match but against someone who tried to throw cheap shots, Against a stranger.
5. And I have this small but cool story about how someone tried to sucker punch me twice and how I came out on top.
6. When people ask me about my experience this one of the examples I can give when I teach and as an example of my ability.
It may not seem like much from the outside, but for me on the inside. It was an honest confidence builder about my ability to physically defend myself. In the context of business, people that I teach self-defense to like this little part of my life. It puts the questions of "can I really use what I teach" to rest. There have been a few moms who trusted me with teaching their son or daughter how to fight and use self-defense. Could it have gone bad. Sure of course. There's a lot of things in life that can go bad, but sometimes you have to trust your ability to analyze others.
Do I think everyone should accept challenge fights? Definitely not. For me personally I'm always honest with my limits. I wouldn't accept one if I had a strong feeling I would lose without the possibility of winning.
