I cannot recall ever asking anyone about their martial arts rank. I did not even like typing the question. When non-practitioners find out I am involved in martial arts, they inevitably ask me if I am a black belt, the style I practice and my rank.
My usual response:
Yes, I am a black belt. I study Okinawa Kenpo and have been training since 1993.
When friends and co-workers find out you practice a martial art, what is their reaction? Do they ask you about your rank? How do you respond to their questions?
