It's been in the wind for a while; attendance was dwindling, Sensei was getting more and more visibly and volubly pissed off with the Kenshukai system, and last week he quit for a rival school.
There's a Kenshukai class in Bromley on Thursdays, which will be far more convenient really as I can walk to it. The fact that I didn't switch classes when I moved speaks volumes about my instructor and classmates; I'll miss the old group and I'll miss Sensei, who is not only a great teacher but was kind to me when karate seemed to be the only area of my personal life I wasn't failing in.
I wish him well in his new dojo. As for me, onward to the next belt!
