Your wife spit her food at out the idea of someone providing the requested example of accessibility tools used by deaf or hard of hearing? Im hearing impaired by the way. Maybe you should show your totally real wife this study suggesting low penetration due to stigma attached using them. Maybe you should ask your wife how she’s feels about people using her disability as an excuse for being irresponsible while driving; though Im super worried she’ll just laugh at me again. Most of my partners haven’t seen or heard of most of the devices I use for hearing loss until they dated me. Guess that means they don’t exist by your definition.
