perhaps it's because you are deaf (or HOH) so how would you know it doesn't happen often?. Fact - yes it does happen a lot. Verbal communication is difficult even for hearing.
No offense taken
That's why we're here to educate you. As we said repeatedly - ASL is a complete language with its own syntax and vocabulary. It's the 3rd largest language in America.
SEE, CS, etc. are NOT a complete language.
Southerners speak in quite a different English syntax. I forget the term called but it's "black" language used back in old days for example.
It's not the accent. It's the syntax of English and usage of certain English words adapted to their style. New Yorker would not understand what Texan says and Californian would not understand what British said. When people do not understand, they revert to "proper" English.
