Thanks to everyone for your recent comments and please excuse the delayed response.
My husband is recovering quite well from his broken nose, thank you! And we've moved on from the incident itself except as a reminder of the inherent dangers in martial arts, and the fact that some people are just jerks! (lol you can tell I've forgiven the guy...). The person in question has a history and a reputation, few if any friends, and as nearly as anyone can tell, doesn't care. What's to be done with such a person? Well basically, nothing. Except hope that over time, he will change his attitude.
I also am recovering, out of the hospital (with a new baby girl!!) and out of training for at least 6 weeks due to recovery needed from surgery. This is probably for the best since I am barely sleeping and would be a menace to myself and everyone else in a dojo! But she's worth it.
Watch out, the next generation hath been born!
