Thank you for the replies! I like that last reply, got me thinking... yes, it is a way to deliver the language. That's true. But it does have it's own way of" talking", so isn't that a language? Very interesting indeed. I want to learn more sign language. I know many baby signs, I teach them to my kids. But I could never meet a deaf person and totally communicate, unless it involved a lot of finger-spelling. LOL
