I know how to do sign language, I have a family friend who is deaf and I chose to do a sign language class, both to help her and it's also a VCE (the Australian version of the SAT test) subject and if you do a language subject, it boosts your marks. :D
I also want to relearn ASL. When I was in middle school, there was this girl in my class, her name was Maria. She was deaf and I wanted to befriend her. So I went to the school's library and got a book that teaches you how to sign. It was awesome I learned how to say like Hi, how are you and random things like bacon, coffee, spoon, etc. Over the years though I sadly forgot how to sign... I want to relearn 1. because of Switched at Birth as well. And 2. because I also want to be a journalist :)
My friend just sent me this video if you guys want to check it out, she also has a lot more signs as well.
