Pokemon Reward

My son is in Kindergarden and they have a system for good behaviour where the top is superior and each day the children start on good and they either earn their way up to superior or down all the way to oops. Well, my son is a talker and usually ends his day on try harder or on good. I am proud of him when he ends his day on good. Well, today out of the blue, he earned a superior! I was so proud of him. I had always promised him if he got a superior, I would go get him a surprise. Well, off to the toy store we went and a Pokemon trading card game he got. He was super happy and I was super proud!
