Re: Futari Gake
In my experience, sensei doesn't tell people when they are being out of line. there is an old man who comes on saturdays that routinely practices in a dangerous way. Most people really hate him and avoid him. Has sensei ever told him to cut it out, no. unfortunatly I don't have the guts to confront him, about the best I could do was say "ouch that hurt" "that's dangerous." Same thing when the university club comes for a seminar. they are way too rough, and sensei never addresses it. The other dojo I practice at is the opposite, people are constantly instructing in a "let's not hurt each other" way. Unfortunately some people take the martial aspect really seriously, and expect others to be on their toes at all times.
finally to answer your question, definitely out of line.
but I wouldn't take it personally, to a lot of people in my dojo, that would be messing around.
