when at seminars or in another dojo, we are taught to wear our white belts. though, not everyone does. i do, though. so, i always get the extra lessons and advice. i find it frustrating at times, but also very informative.
it's also funny how new aikidoka and other students from other arts treat you. you're usually over looked because of the obi you wear. it's kinda sad.
i emailed my sensei the other night about this same topic. lol what a coincidence!
