Aikido is a martial art that is a sport like no other! Also the masters of Aikido will not make you stronger if they don't kill you, they will definitely kill you if you push the wrong buttons! :) Just kidding...
So if you're not an Aikido master and therefore not different in that way, I would suggest that that you don't try and be different than normal towards any Aikido master.
Agresiveness won't get you far, on the other hand if you run like an olympic medal winner girl, that will definitely get you a lot further.
Or you can get this aikido shirt and pretend to be one! :)
