There was a student that used to go to our high school were I sub, he is now dead I think, that looked like he was in the 4th grade or so. He was going to school at the high school in a special ed class, and the aids told me he was 17 years old. He had some serious disabilities. When I asked what happened to him I was told he was in a bad car accident and never grew any after that. He must have been about 10 years old or so and was as if he were frozen in time, never looked older than that. GH must not have been released, never went through puberty. The wreck must have been real bad. It was one of the saddest things I have ever seen. He couldn't really talk either, no speech. One day he just stopped coming to school, he finally passed away.
