When I did a placement at W. Ross (a school for the blind in Canada), I came across that a lot. I found especially that some of totally blind kids didn't understand that glass was see through for people with vision. More than once, I stumbled into a couple of kids making out on the other side of a glass wall or something else.

I also had a client (mid-twenties) who would not believe I could see the distances I could see (a block or two away). It blew her mind that I could identifty a car was coming 20-30 seconds before she could hear it.
