My wife went in a hearing aid shop that had just changed hands. The new audi there does not know a single finger spelling. Since my wife's earmold broke, and she could not hear a thing, plus her lipreading skills are not all that great, guess what that audi used to communicate?
WordPerfect. Yes, Freaking WordPerfect on her computer.
Both took turns typing. The audi got tired of writing.
Things could have gone smoother if that audi knew some signs, but no. The worst part was the audi seemed irritated/bothered that she had to take extra steps.
Even my "new" CI audi doesn't know diddly about ASL. She was lucky I could read lips.
There are millions of ASL users, it would have helped if most audi's could practice some.
