Re: your number one technique
What an un-aiki behaviour!
You should scold your son before is too late, he's acting like a gentleman. If you dont bring him back to the right path of aiki as soon as possible, before you notice he coud go into the nefarious ways of scholarship.
Imagine the disgrace for the aikido world if people started to consider your son "a gentleman and a scholar". Him being a fighter is not enough?
