True dat. I've been thinking alot lately though about the difference between a "sensei" (a la aikido) and a "coach" (a la BJJ). I've had immense respect for my Aikido sensei down the years, no question. But my BJJ coaches have become friends very quickly and I can't say that's happened in Aikido. Although some of my students have become friends. So maybe it's not a sensei/coach dynamic but a western/japanese one. I certainly find the "friendship" based model more effective for both learning and teaching however.
