But as gratified and so many of you wrote...a lot of teachers rarely if ever encounter a truly HG kid. So my friends' experience is the norm.
The way I've put it before is that I can't blame others if they think I'm nuts, since I so often think it myself.

HG is really really "out there" and even though we've got these kids around all the time, making them look pretty normal to us, no one else has that. It's not surprising that ours come across as somewhat unbelievable -- they really are tremendously unlikely!
Hmm. I suppose that 1:1000 or even 1:500 people are extremely rare in individual environments, but if you look at the population as a whole, there are a lot of them (~300,000 of the 1:1000 group in the United States alone).
From where I sit, that's a LOT of people, and schools of education should be addressing this group, not allowing their graduates to pretend they don't exist. These programs devote time to the severely disabled, who are the other side of the 1:1000 groups, right?
