When a certain Pekiti-Tirsia practitioner challenged a Modern Arnis Datu for disrespecting GT Gaje. And this Pekiti-Tirsia practitioner gave his name, address and a place to tango, this was an open challenge. Disrespect is a good reason, very old school. All the poor Datu did was hit the ignore button, like an ostrich sticking his head in the sand and saying "there's no place like home, there's no place like home". But the damage was done, everyone saw the call out and the cowering. The word cower definitely applies here. When somebody calls you out, and you're a head of a system with everyone looking at you, you go yourself or you send your number 1 who matches that challenger's skill and level. That's how it's done in the Philippines. Today, they still do it .
