We had just finished with a Taekwondo belt test, and there was a green belt waiting for his parents to be ready to go. So I pulled him onto the mat for some light sparring. This is a kid that a few months ago was very sloppy and unfocused, but he was doing really good. His tactics, timing, and accuracy have gotten a lot better lately. Well, I decided to do the thing bullies used to do to me when I was his size: put your hand on their head to keep them at a distance so they can't fight back. This kid just turned his hips in and roundhouse kicked me right in the side. 6-year-old green belt taught this 30-year-old 3rd-degree black belt a new trick. Something I wish I knew when I was younger.
