So I was at the Worlds. I learned a lot and I mean a lot from everyone, and the stuff I saw made me love the art, not just the sport of Jiu Jitsu, so much more. One thing that will always bug me though, is the guy that didn't say excuse me, when he bumped in to Rickson. I'm still debating what that was all about. This leads me to an important question in regards to martial arts etiquette. Is it me, or is doing what that guy did, regardless of what school they are from, an absolutely horrendous act of disprect. Or has the alliance/gracie rivalry come to this and we should accept it? To me it's just huge amount of disrespect.
