You guys have an oath? The mr/ms and sir/ma'am is more formal than I'd like, but common enough. But I don't think I've ever seen an oath that's said at the beginning or end of class (nevermind both). Is this a normal thing in TKD?At the school I attend we use Sir and Ma'am to address everyone. All black belts are addressed as Mr or Ms then last name. When we recite the oath in the beginning and end of class we start and end it with "Sir" as our head instructors is male, out of habit when on the occasions have a female instructor many will still say "Sir" which is always good for a chuckle. Most times the female instructor is understanding.
