@Thomas,
Right, that's very possible. And even most likely.
But I'm not certain of that, from the information given. I
know, from my own experience and from working with many other people with many other disabilities, that there are people who decide that disabled people can't do what they actually
can do. It just doesn't seem possible, so they discount it -- or maybe there's just that intangible ick factor.
I'm not accusing this coach of that, because there isn't enough information. But it's also very possible from what limited evidence I've seen thus far.
