We can notice the intend of uke easily, can't you?
Some ukes are trying to help us learning proper techniques. However, some other ukes are just trying to tell, "Oh, boy I'm better than you." In that case, I simply ignore such rude guys.
Of course, many newbies are very annoying, but it's just because that he/she is a newbie. Then I simply said, 'Take it easy'
ps. YoungIn Park seemed a Korean aikidoka like me.
