I'm pleased to say Z received his blue belt as did his best friend.
Z has been going to Karate for 3 years now and he's done really well to get as far as he has. If he carries on like this, he'll be a black belt before he hits 18.
He has a competition next weekend which we are all looking forward to. However I think he will be in the same category as his best friend which means they might end up fighting one another. I'm not sure I'll be able to watch that one!
