 Jeffrey Modell Foundation, helping children reach for their dreams. Visit info4pi.org. When I grow up, I want to be a teacher because they know a lot of awesome stuff. I'll stand in front of the class and make sure everyone knows what I know. If your child is sick over and over again, it could be PI, a serious defect of the immune system. Early testing gives children a chance to dream. And when I'm a teacher, my favorite subject would be recess.
