 Well, I've told the story before. My son was in middle school, and he got in trouble for calling his teacher, sir. Because, well, again, he was doing karate with Tony Fournier, and Tony is a great guy, and he instills the respect. And it's a mutual respect. They said, when you address me or you address any of your senseis, it's yes, sir, yes, ma'am. But respect is a two-way street. So they called the kids, yes, sir, yes, ma'am.
