Well I spend most of my time at school, Well I spend most of my time at school, but when I’m not at school I am most likely but when I’m not at school I am most likely at the natatorium! I am on a diving team at the natatorium! I am on a diving team called GC Divers which is currently 3called GC Divers which is currently 3rdrd in in the nation. We practice in Keller, Texas at the nation. We practice in Keller, Texas at the KISD Natatorium. So, the point I’m the KISD Natatorium. So, the point I’m really getting to is being at a natatorium is really getting to is being at a natatorium is my world, so here we go!my world, so here we go!
