From this date in 2011:
Brian J. Noggle just tied the karate belt on his son’s gi based on an eHow tutorial. Noggle hopes this is the traditional way and not the one that signifies the wearer wants to challenge the sensei to mortal combat for the right to lead the dojo.
Of course, he’s not wearing the knot. So it could be worse.
Followed by a comment later:
Well, two positives from this faux pas: 1., perhaps the avenging his brother thing will encourage the younger son to study Karate more dilligently. 2., I made $5 betting on the sensei.
A year later, the younger brother would start classes. A couple of years after that, mommy and daddy started taking classes. In 2022, 3 of 4 reached black belt rank, but only daddy still takes classes there.
