We should teach deaf people how to read braille so that they can become pen pals with blind people. Likewise, maybe we can teach blind people how to yell really loudly so they can “talk” to deaf people.
I’m not sure that those two concepts are exactly compatible with each other. Someone sends you a letter wishing you a happy birthday, and you respond by screaming, “THANKS!” at them.
If their deaf friend is a really long ways away, they could call them and yell into the phone. Do deaf people have phones? How do they know when their phone is ringing? Do they answer it every few minutes just in case someone is calling them? What if they answer and it’s their blind friend calling to wish them a happy birthday, but they don’t understand braille because they never learned it at their deaf school?
The trouble with the world today is communication. Too much communication.
