Congrats !! I still remember when I was finally able to take my first ASL class ( I went to a hearing school, "mainstreamed" without any support, before mainstreaming had a name here. My parents were adamant that I didn't learn any sign because then I'd be "like them" (hey !! what's wrong with us ?)
I , like many of us "oral-onlies-not-by-choice" had managed to sneak a number of "sign language" (a mix of SEE, and ASL) books which I memorized like crazy ... but I couldn't use...
being able to sign up and take my first class felt like I was finally able to breathe !!
My mum eventually came around too and took many classes as well !!
Congrats !!!
