Good you took the test, and congratulations. I remember my Dad saying, "Get the piece of paper." I don't know whether it was an M.A. in an exotic European language that came from Asia (Hungarian) -- passed the test but would have had to redo the thesis..... went to work for Dad instead....
Anyway, still like the language but never did complete the thesis, worked for Dad for over a decade and studied Aikido while in N.Y. but I am happy to say we had a senpai T.K. Lee who always made sure we took our kyu tests. In your case you were definitely ready, but as for myself, I feel the urge to confess something; The previous test was, I think, the first one with freestyle, I can't even remember whether it was one or two ukes. I didn't spring to my feet soon enough and trying to do tenchi nage it was like two pieces of sheetrock not knowing which one was going to fall back. I let out a yell and managed to be nage!
Wondering if I failed due to being caught off balance to start with, I was swept up with the group into cars going uptown to a restaurant. Sensei was in the front seat and I was squished in the back between two or three others, and it was if one eye swiveled back at me, or maybe was even looking straight ahead. But I heard him say distinctly (his accent is way gone by now but this was decades ago) "You didn't scream you failed the test."
Well, that was somethingl In a dojo that didn't go in for a lot of kiai shouts, it worked that time, or at least it was accepted and I passed.
Sorry to be so long winded, but there's a bit more. I thought for sure that I would skip the next grading, having been caught "flat footed" so to speak (even though kneeling to begin with) at the previous test. So Lee in looking us kohai's over, said to me."Take the test again" He knew it was for the next kyu rank, but he wanted me to go for it, not to hesitate or hang back from the experience just because of awkwardness, mistake or whatever on the previous one!
It's nice to be over-qualified, but even if not, it's good to have a senpai encouraging a person to go ahead anyway.
Glad you took it, and then right into looking after, and enjoying your family. That's the way it should be!
