Jack is always very cocky...Aiden and I needed the mats to train a little bit and it was schduled like it... sometimes jack is renting my place to train too, but this time it was suppose to be our hour. he didnt want to leave the place, so we had to show him who were the bosses! :-) he was still cocky at the begining and fought back but we found a way to be in control and dominate him all the way!
