Haha, someone asked me once why I wasn't mute and why I didn't "talk retarded." No lie, exact words, "talk retarded." I was like...you're kidding, right? They were like "Well, no, Helen Keller couldn't talk!" :roll:
I have been asked the same question, and also told "But you don't sound retarded. Deaf people sound retarded." :roll:
I might add that Helen Keller was an oralist and made a point to learn speech and use the Tadoma method (tactile speechreading).
