That was pretty cool, and like others have said both of those kids will be mighty when they get older.
However, I always find myself wondering how fighters prepare for these types of fights, given that they end up sparring with rules that are totally different than they would be held to in their own dojos. If you never take or give shots to the head, you are definitely at a disadvantage when sparring someone who can, and does, at every class. Same with the sweeps and flips and all the rest. Anyway, great youngsters with great hearts!
