Karate Class

We enrolled Ben & Nathan in a Karate class and they have learned some good stuff, but it mostly seems like a babysit the kid type of class since the teacher has them play chase/runaway games and avoiding a ball being thrown at you and reading stories about an animal being bullied. There is some Karate taught, but it seems like a lot of Wax on, Wax off and I'm starting to wonder if theres going to be a revelation of oh we just learned karate. But they are only 5 & 7 so I guess that its too early for them to learn how to rip someones head off. LOL
