@boomerang,
Yeah, me too with my mother.
A similar but different attempt at increasing understanding re disability: a pal of mine (we were design students together and rose in age and grace, career wise) ended up teaching at our school. I can't remember the exact class, but he had made the land site design students get around the big and not flat campus in wheel chairs, the idea being for them to be wiser about the problems of it all.
