Ron, I believe she just made a simple typo, as she also spelled it right previously in the entry.
I'm sure we all know about my typos in here. HAHA.
Yeah, it was a typo. Sampai is a turn me use in my dojo, so I use it. Though the word junior/senior/ rank etc are all acceptable.
I think most of the issues we deal with with "junior" students is those who might take themselves to seriously. Most people in my school at least, if they mess their ukemi up and you respond by changing the technique to correspond the uke is fine with it. They might either find the lesson of it, or find the humor of it. They enjoy training and the process. Now I'm not saying my ukemi is spectacular; note my flexibility thread for proof of that; however sometimes people purposely take bad, lazy, or defective ukemi. When they walk out of a technique, they splat before you even touch them, or try to muscle you down with them when they are thrown it can get dangerous if you don't change what you are doing. And I've come across two people that scream and make a scene if you change what you do in response. They fain injury, or get beyond flustered that they were "physically" corrected. I think maybe they are taking it all too seriously.
BTW: when someone refuses to let go when thrown quite hard I've yet to fall with them... I'm luckily very low centered and naturally low to the ground, and I had an instructor that held on to me when I threw him to teach me good posture and good stance since I was a 6th kyu, so I've yet to land on the buggers. (I don't trust their ability to get out of the way if I fell on them, which makes me think it is a stupid move on their part even more so.)
However, the person that likes to hold on to me just for the sake of being a difficult uke hurt her shoulder. I had good posture and finished low, she was still holding on. My body didn't give to the force but her shoulder did. I really didn't consider her trying to "prove" she was more skilled was worth sitting out to her or anyone else. It just frustrates me. I wanna scream "What is the problem? ! Just train and stop thinking your anything you're not, enjoy yourself and don't take it so seriously. I mean seriously, at 5th kyu you aren't going to impress anyone anyways, so cut it out!" I mean lol, I sure the heck don't impress anyone, I'm not going to break my neck trying.
