Go ahead don't. My friend John, both his parents are black belts, and his brother is also a black belt. Taekwando. I took it for 2 years, so I'm not that great, but I'm not exactly bad either.
But... I have had a big guy come after me... for reasons I won't get into. Well, let's just say most people won't fight you when you pull out the set of throwing knives you have in your pocket. And yes, I usually have them on me.
