Although I've been at it awhile, I have not tested for the "yudansha ranks" and continue to wear my white belt. Needless to say, I run into this all the time. Especially at seminars. It's a shame really because learning is so much better when you can have fun at it. Some people take themselves way too serious.
We are very fortunate in that people that train at Shindai are very enjoyable to be around and they all have a great sense of humor.. they need one working with me! HA!
Sensei creates that enjoyable environment, we just try to enhance it...
